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.

1998 Mercedes-Benz SL500 Reviews

Rated
based on 2 customer reviews
1998 SL500 with 123k miles now. It has 32 valves and dual OHC. A pleasure to drive. From 1999 through about 2008 I think they have one OHC and 24 valves. I love the car but its like a mistress that always wants more. At 99,000 miles one hydraulic roof cylinder (they raise and lower the soft top) went out-1800; at 107,000 the transmission went-4,700 at AAMCO: to be fair, it may have gone out...
very good condition, low miles
