1998 Mercedes-Benz SL500 Problems

Miscellaneous -- Verified

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.

Drive Train -- Verified

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

Suspension & Steering -- Verified

The lower control arm bushings can wear and crack, resulting excessive movement at the control arm pivot point, leading to irregular and premature tire wear. Worn Ball joints can also cause similar tire wear symptoms. I some cases it may be necessary to replace the lower control arm, including bushings & ball joint to correct this concern.

Brakes -- Verified

As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.

Suspension & Steering -- Verified

One or more of the following steering linkage components may wear prematurely;  tie rod ends, drag link, or idler arm. Our technicians remind us the wheel alignment should be checked and adjusted if any of these items are replaced.

1998 Mercedes-Benz SL500 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 because a Dealer "flushed" the transmission which experienced people say not to do if you haven't done it regularly-it forces contaminants into the system: so 3 weeks later it went (I know now not to let anyone flush the transmission); the ignition lock jammed at 115,000 miles-1800 at a dealer; while the lock was under repair, the "soft top module" went on the fritz preventing the windows from closing completely: the dealer wanted almost 3,000 to replace it; I declined and read up on this by googling it; in a few weeks it went back to normal again, as I suspect the dealer knew it would (the soft top module goes haywire when a battery is disconnected-usually resets in a few weeks, but when it goes bad, its hellishly expensive to replace); engine work: 4,000; new flex discs; suspension repairs; seals that leaked; and on and on. Nothing is cheap to fix on it, and things you've never heard of seem to go bad suddenly--no wearing down, it just goes. I did learn-duh-to avoid the Dealers, since their prices are 3 to 4 times a good repair shop. Example: An ignition coil repair (like a spark plug) is about 400 at a dealer, 300 at another place close to work, but only 189 at the place I go to now, and their work is just as good. The 1994 S500 -a big tank of a car-was more durable than this 1998, and things rarely stopped working on that 1994. Benz has, I believe, downgraded its components and sells to new car buyers and is not interested anymore in anyone who keeps them after 60,000 miles. Can't say that's bad policy, but beware: My advice: buy it new while its covered by a warranty, or be prepared to spend a lot keeping it going.

very good condition, low miles
