Buyer’s Guide to the W126 Looking for an SEC?

Don’t be in a are lots of nice ones out Options include 4 place seating in sedans, metallic and velour seats (few US opted for) as well as seat lumbar support and the electric rear window (rare).

Colors I have and recall (there could be are gloss black, pearl cabernet, lapis blue, blue, white, cream, red, gold, silver, (gunmetal gray), smoke 1986 cars on have the same equipment as up to 1991 dual airbags came out in ’89 and ASR in ’91 I ASR is not a necessary option.

The largest best kept, rust examples will be found in California, especially Los Angeles. The selection there gives you a price break too. The S is the “staff car” down When you are ready don’t to ask for Carfax report, VMI from the and get the car inspected.

Fewer and fewer are up on MB dealers lots, don’t they have slid out the of the Kelly Blue book. problem areas are the notorious radio, the power window and Air Subtract from the price if the AC work. Other than the cars are pretty bulletproof, but are a little expensive, especially the trunk and hood.

A stock 560 SEC 0 to 60 in 6.9 to 7.1 seconds. But they respond to after market mods, lowering and AMG exhaust. However if I you I would look for one in stock with all books stamped, and available.

First, there is no “bad” from 1985 to 1991. You to be aware of the differences, such as the (500) motor is substantially than the 86-91 which have the 560 motor. If you must the 1985 motor you may save if you would like to buy one in the 85 year. be cheaper but there are reasons- of them. Thus, basically any 86 to 91 car be a US model, for the gray market ceased to exist in 1986.

SO, the thing you need to do is to take a look at your budget. How do you have to spend, here: The end, -12k will get you a 85 with high miles.

On the end, out here a 1990 SEC 7,000 actual miles, so new it had traces of cosmoline on the motor, on the market here in San Jose in for and it sold in 3 hours to a fellow in who bought it for the asking price, he on a plane and came and got it.

That you will probably need to out where your budget fit. With a car like the general advice seems to be you should pay at the beginning, the most-for the can afford, i.e. the newest, condition one you can possibly afford. The for that is that a bargain can quickly prove to be no bargain at all if you get extensive repairs right

To this end, perhaps would be a car in stock condition, by a fussy single owner ALL books and records.

Don’t to run a CARFAX report on the car, ( on the ask the dealer for a Vehicle Master on it – to show all repairs done at a under warranty, then you call 1-800-For Mercedes and ask to give you a copy of the original sticker-that will also you the dealer first delivered to.

in the books and records and call up the who worked on the car. If you are lucky you can get to at the actual repair orders, they are still around.

I told people over and I believe the safest source to for cars is Los Angeles because are best kept, the market is with them, the body and shops are generally most and the weather is most agreeable for them, and the prices are lowest and

the is widest because there are so of them around down The very very best even still are occasionally at Mercedes dealers down

As far as problem areas there are When I did join the list I did ask and read the buyers guide and is what I know.

Problem are…

These cars are bulletproof if you take care of If you don’t, they will a mint to fix. Therefore, be you get one that can be documented to have well kept, and you do the same.

one of all is the air conditioning. If the car you are looking at, the AC work, I would IMMEDIATELY off the price, because it could this much to fix. if-in some cases, all it is a new fuse. You can almost expect a here. Don’t be surprised.

First, take your I don’t know where you but around here it is still to find terrific examples. a dealership might not have one for you on a given day, take time you’ll end up seeing a of them.

Second, Ignore how the car looks cosmetically. The paint and materials are of such high that an amateur with 6 available on a Saturday can make a wreck of a car look great. Six at a professional detailer you’d that that ‘pig in has never seen daylight, it just arrived from gorgeous, breath-taking, looks it’s never been sat in.

make sure the car has well records of all service. If somehow errr… become separated the car’, separate yourself the premises. These are MB’s model, therefore the most version. I’ve seen who buy them and then can’t to maintain them, so oil changes and things get put off, in addition to the big

Fourth, have the car inspected by a who is specifically very familiar ’90 – ’91 560SEL’s.

I tend to be overboard in how I maintain my and based on how it’s running, I’m to get 250,000 miles from the before any major work is While the trans operates I’ll be pleasantly surprised if it it to 250k, although Stu Ritter has that he has clients who’s last that long or

At 250k if I find that the and trans are toast, then a decision, as I suspect I could a rebuilt engine and trans MB for k and be ready for another 150k

While that sounds a lot, I could spend k on a Taurus and I doubt I’d get an additional miles out of it with the same of reliability and safety. Knocking on my 560 is a wonderful car. Things to be tended to from time to with me budgeting a year repairs / improvements, and so far it’s wonderful experience.

In addition to an incredible car to drive, I feel safe using it to drive and friends as I consider it a very car. It also has it’s but overall I’ve found it to exceeded my expectations and plan to own it for more years. Hope helps.

Purchase a car that has up to date service books/records There are simply too many of cars on the market today – have been meticulously and preferably at the dealer – to buy one that has even remotely neglected. If the car considering doesn’t have books that are up to the minute, a turnkey solution:

Go to several dealers nearby in person and say to the new and preowned sales people. them you’re in the market for a or perfectly maintained w126. them what colors like and the mileage you’ll Put it all down for them on a piece of with your name and

They’ll know you’re this way. Next, them you’d like help in finding a nice car and you’d be happy to pay them, or if you buy a car they locate for you. tell them that you are about buying by XX and XX date, and if one of their w126 clients like to come into the to look at a newer or new Mercedes … you’d be happy to meet at the dealership to examine their The word ‘new’ should up their ears.

If you do the above, the person will take you and most likely contact of their clients to alert of a prime opportunity to ‘move-up’ and or lease newer car. A sales person would be not to consult his or her Rolodex for existing owners who may now be ready to do so. Perhaps an couple who haven’t driven but are ready for a w140 or a 2000

You’ll be presenting a wonderful and moment for any good sales to do some win-win-win work — and get what you want and deserve a w126 in the bargain.

The engine in the 560 is a 5.6 v8 and the engine in the 420 has a 4.2 liter v8. The 420 is fast! The 560 is Both are heavy on the gas if you are heavy on the While keeping an eye on your consider very seriously the extra few thousand you’d on the 560 – to buy a 420 that is in even better

Both of these cars are to own and drive – provided they plague you with annoying costly) problems that are to arise if the books are not up to date.

I we’d all be surprised by the number of driving badly maintained “S” cars. They may still nice on the outside, but get under the or inside the cabin of most on the road today … and I’d bet half of have inoperative A/C, gear and troubled mechanicals.

Not poor engineering! But from a of maintenance by able wallets. The muffler on my ’87 420 was CDN at the dealer several ago. And if you put after-market stuff on the car no longer a true Benz and most likely perform

The question is – do you want a real or a problem on wheels for show? If you go a well cared for w126, all up to date, I assure you this car impress you Every time you and drive it. In my opinion — which is shared by many 126 owners if not all them — the w126 is a phenomenal car makes most 2000 year vehicles (by other pale in comparison!

The w126 is phenomenal (still readily me after 10 years), the engines are high speed steering is and perfect, high speed is even more breathtaking, the of the 126 is prized by all Benz mechanics as some of the most trouble-free and that Benz may ever – just ask them.

Let’s it, parts wear out. only natural. The self on the 560 has not been a problem. But yes, it wear out – and cost you a goodly sum it does as compared to simply the shocks as you would on a 420 — an easy, job. If you’re wondering if a 420 is comfort able than a the answer is no.

I’ve had 5 passengers in mine for 1000 km trips with luggage and the ride comfort is to any other car I’ve ever in – save for a Rolls, Bentley, or In fact, the heavier your the more comfortable the car is on highway It just hunkers down and to the road like glue – exacting precision.

Long cruising in a fully laden S at speeds above 140 mph will quickly impress you and turn you a lifelong Benz lover. Try in a 2000 Cadillac at 4 times the of a ’90 S Class … You won’t be near as or as comfortable.

You’ve probably fallen in love with the 126 – buy one that’s been wonderfully (no ‘ghost’ owners, forget the cars that are priced good to be true’) and the wonderful will last forever. more, a pristine, all-original with gleaming paint and in factory condition is still the most elegant sedan on the today.

P.S. If the tires replacing at the time of purchase, is an excellent opportunity to shod the car new “V” or “VR” rated tires. “V” tires will make you a happier 126 owner. Plus, you can a few dollars off your purchase when you tell the seller the need replacing soon. If like to hear more my experience with great on the w126, please feel to e-mail me and I’ll send you a of my recent post at the MBCA Forum.

Before buying my car I to a person at Hatch Sons who me that starting in ’89 the camshafts had a surface and therefore weren’t as to failure, but I’ve never able to confirm that so not sure if it’s correct or

These are great cars well maintained, but complicated/expensive to fix not, so just be extremely about having a really PPI done by a mechanic who has had years of working on 560′s, with a or leak down test.

Be suspicious if it’s the least bit or doesn’t drive idle – when right, these are silent smooth as glass. it’s typical to see evidence of dampness on the underside of these due to miles years, anything a slight dampness should put radar on full alert.

And any 126 chassis S class, the suspension be quiet as solid as a rock; the hydraulic system on this car is This was MB’s flagship therefore the most complicated they had, but a car that a smile on my face every I drive it.

There are many well maintained examples of cars around, so unless the is good and all service records are for your review showing not normal OF changes, but all the normal that should have fixed over the last 13 I’d be wary.

Maintenance Schedule

I am suggesting an aggressive maintenance It will save you in the long Based on my conversations with Mercedes owners in questions to the lists I would do the following

Oil changed each 3,500 – for sure if dusty or city

Air filters and fuel filters (2 filters) about each miles

Auto trans each 15k to 30k -depending on kind of

Brake fluid flush a year or 12,000 miles comes first. It really get dirty but the std is so rigorous because of 150 mph stops on autobahn, I guess

diff fluid each for models with LTD slip – use the Mercedes Ltd slip diff it is 90w

Tune up: new plugs each15k or 30k you feel is better

YES, even the power steering and filter each 20 or 30k, is not even in the owners manual but do it now or pay for a new later

Every 30k change the in hydraulic rear suspension or you risk big trouble on these. mounts last at least 50k but be watched

Wheel alignment each 12k – if necessary This may like a lot but it is preventative maintenance and you be rewarded with a reliable car if you care of it

Now then: I would shy from one needing body This is super expensive to done to the proper standard. more so than repairs.

Basically there are cosmetic changes beginning in 1989. I most models are fully and that means ABS and airbags, I in 88 or 89 they were dual but I am not A model with a dual won’t have a glove that is how you tell.

From I recall that the options are few – included on the 91, anyway, power electric rear window velour (Few US customers metallic paint, reinforced frames and a lumbar support in the seats. For ’91 only you could traction control- something I would not want. Make the car you buy has its tool kit, first aid kit and tire and jack in place.

is mixed opinion about the cars to handle well. believe Mercedes designed to handle best with the tires and wheels the car was supplied believing the suspension geometry was this way. Others the aggressive look and handling on a car with wider bigger My car was like this and I have over the years to enjoy the springs and 50 series tires.

I this helps. It is my opinion but at least it is a start. I have regretted buying this and it will save my life in a too. It is as unremarkable at 130 MPH as at 60 mph. ask me how I know. ) Feels solid as a I love the thunk of the doors as shut. home.

I cannot I thought about a new Volvo 960 and a Towncar when I was looking. is definitely the ride for me. Plus, is a dedicated following of owners to with questions relating to my of the car. To that end, you may me again. Hope this

One thing I forgot, and it is important: the timing chain, tensioner rails at 100,000 miles. If the stretches and breaks or jumps the (more often on the left it will cause a huge a engine rebuild could be the More preventative maintenance…

Maintenance Advice

At 65,000 you should check – and CHANGE the rear diff and power fluid, if no proof they changed within last 30k it now. Same with trans fluid and spark ORIGINAL. You should change the timing chain and guide at 100,000 miles.

Behr has unreinforced hose necks, can crack and cause catastrophe. At 75-100k just put in a replacement whole new radiator, view as a item. The replacements have hose necks, so unlikely to be a again. These cars ask for a brake fluid flush, fluid ought to be changed other year USE ONLY coolant).

You can go3500 miles oil changes, I would not go more that though between I would start watching the mounts now and the steering damper Perhaps change them out at miles. This may seem a lot BUT if you care for the car well it ought to you forever and look new all the time.

maintenance cycle every miles, with a big one at 60,000, and every 15,000. All of these have been done “by the Keep in mind that you are a car that cost something K new. You can buy it a lot cheaper, but it still maintenance applicable to a K car.

Any problems with the self on this beast? None in There is a hydraulic fluid and pump, using special oil (all this I understand from Citroen DS/ID and the oil and filter want changing so often. There are nitrogen that give up the ghost a while, but they are not that to replace. Unfortunately, this of system tends to baffle the Joe mechanic, and you’ll want to run it by who knows these cars out.
