1992 Mercedes-Benz 500SL Problems
High mileage vehicles may develop a transmission fluid leak from one or more of the oil seals.
As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.
The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

1992 Mercedes-Benz 500SL Reviews
As our family (kids and grandkids) walked out of the local pizza restaurant, we passed a red 500 SL. My husband and I have been shopping to replace a 96 mini van with 280,000 miles on it, and have looked and tried about every car out there. Go for gas mileage? comfort? But imagine his surprise when we gave him a set of keys and told him it was his! He is in heaven, and I will drive that minivan to 400,000 if I have to, to keep that beautiful Mercedes for him.
Bought this car from Mercedes dealership in Omaha about a year ago and love it. Certified mileage 27,400 and the vehicle is in mint condition inside and out. The sticker price of $99,750 in 1992 came as a shock and is the reason why this baby performs and looks like a world class sports car. The only problem that I have is the fact that this 500SL spends most of its time in my garage, which is 5 or 6 months in the winter and if there is even a hint of bad weather the rest of the year. I have only put less than 1,000 miles on this dream machine, but they have been the most enjoyable miles I have ever driven. If you can afford one, run do not walk out to get one.
