I meant which year production has the least reported problem? Which year model to avoid? Mainly meaning either S500c or CL500. Thank you.

Though results are random at best, most users recommend 97-99 models since alot of problems have been ironed out, etc.

Any [MY] 600SEL/S600's are to be avoided, unless current owner/dealer can provide detailed records about the religious maintenance and major repairs already done. That, or you have several thousands in reserve for whats to come

The older ones do have some problems but for the most part the entire line is plagued with them. Evaporators, wiring harnesses, etc

The older ones were built with a "price is no object" attitude. The newer ones were subjected to cost cutting measures that make them not quite the massive diplomatic corps cruisers the earlier ones were. The body was lowered and the paint was changed so that the bumpers and body panels match. All this was done to make the car look "smaller"

Sadly there really isn't a good year for that car - between ASR, bad transmissions, suspension systems, etc. they managed to screw it up every single year.

The general consensus is that newer cars are better so in the US 97 and up. But the build year is no substitute for a well maintained example with good service history.

1994

It has all the bells and whistles -

Back-up masts in the rear 1/4 panels - not available after 1995
Power Rear-View mirror - not available after 1994
Reclining Rear Seats - optional after 1995

1996 + has:
Coil Ignition
5-speed transmission
New HVAC controls

Some will say that 1998-99 are the best years because things have been "worked out." But a low-mileage example is not likely to have any age-old problems worked out.

Any 12+ year-old W140 should have a new wiring harness and evaporator by now.

The pre-facelift models are worth a look. They have a different interior after 1995 and it's mostly apparent in the materials used for the dash and doors. The exterior difference on the facelift is noticeable in the trunk, clear front turn signals, and lower rocker panels - among other things.

Just make sure you find one with a service history.

Later models also has:

BAS
ESP
Side Airbags
Armrest Cupholders
Parktronic(option)
Xenon Headlamps

In the end, its build quality vs modern gadgetry. pre or post facelift, im sure you'll be content with your final decision :thumbsup:

The A/C evaporator plagues all years from 91 to 99.

The engine wiring harness issue was resolved in 1996.

The best choice is definitely a 1998 or 1999, although a 96 or 97 with an good service history and low mileage is not a bad choice either.

Ok, thank you all for the helpful information. I once had a 95 S500 coupe. Sold it due to some finance trouble back then. Now, things are better and I kind of miss driving the bank vault like coupe. The W126 was my mother's car and she passed away last Nov. So, I will keep it just to remember her. But I'd like to get another CL in the near future.

 

[vvee12]

how did you like your 95 coupe? Was it reliable?

 

[Labik34]

95 Coupe is the best

Mine has almost 90k and no issues at all, but i would vote for 95 or 99.

 

[dtkw]

my 95 was fine but little things like the spark plug cable, seat control unit...can double the cost of the W126 easily. But with may companies like Stoprepairbills and USFidelis now available to cover 15 yrs or younger cars. I might consider one of them if I get one later.
