1994 Mercedes-Benz SL-Class SL500 2dr Convertible


This is my 3rd MBZ, one of the best, I love it and I intend to keep it as long as I live. Has 210,000 miles now. Engine runs very quiet and smooth. The soft top just gave up. At the same time some electronic parts and sensers are started giving up. All the aging problems surfaced when we had 110 F temperature days this year. I know what the problem was and need to be fixed but the MBZ test unit never found the problem, the tester always reports as no issue, it is like taking the car in and getting back unfixed. Anyway I told the mechanic just change the part I pointed out and that was it. Runs like a champ, no more heat related malfanction. I want to get at least 300,000 miles life.

Best Features

The acceleration. It is like telling where to go to all these people cutting you off while entering to the freeway, just floor the pedal those bad blood drivers are like a little fly on the rear view mirror.

Worst Features

I did not experience it yet during my 210,000 miles life, but my mechanic tells me that these cars should be recalled for the wiring harness. It is a horror story, the way that the wiring harness is shielded it just disintegrates, bad engineering, it is like a time bomb.

If you still have your SL500 and haven't changed the wiring harness yet., I had the same problem with my 94. I as told about it and found a pre owned harness in Chicago that was the "good" one (manufactured for Mercedes). Apparently there were two different manufactured harnesses for these models. One was crap and the other was good. I had the harness shipped and I installed it myself (not easy) and no problems.
