Some models have tandem hydraulic pumps—one section for power steering and the other for suspension adjustment. These pumps are prone to leakage from either section.

1998 Mercedes-Benz SL600 Problems
An engine oil leak may develop from the oil level sensor. Replacement of the leaking sensor will commonly correct this concern.
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 brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors. The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).
The electronic throttle assembly may suffer an electrical failure. It is often cheaper to send the valve to a service center for repair that to purchase a new part.

1998 Mercedes-Benz SL600 Reviews
This is my view on these machines. I have a 1998 SL600 and her name is Lisa (as in Mona Lisa and yes, I name my automobiles).
Please, remember that these cars are not simple Ford Mustangs or Mazda Miatas with hood stars. Mercedes SLs are cars for people that understand and/or enjoy complex machines (or that have mechanics that do if they don't). Think Swiss timepiece - Not something you just buy to tell time with. If that's what you're after, get the Mazda.
You also shouldn't buy one if you are bargain shopping or trying to impress someone - especially if you can't afford the fuel costs or maintenance. You'd be better of training on a simpler, cheaper automobile. Personally, I love them to death and I'm very mechanically inclined yet I still get goose bumps when I think of changing the plugs or playing with the hydraulic suspension on this V12.
However, if you are ready for one of these beauties, they are a real pleasure to have and just like anything else that is well made, they were designed by engineers that know their stuff and these cars were built to last with expensive materials and highly skilled labor.
You are making an investment with a Mercedes S-class or SL. Buy one that was taken care of properly by someone who loved it then you do the same. Keep in mind that this is a machine designed and built by humans - not gods. There will be problems. There always are. It's just a matter of perspective.
