Great car, but not long ago the tandem power steering pump had a catastrophic failure and total fluid loss of of nowhere and that was quite expensive to fix with the $90/hr labor rate. Now the self leveling suspension valve is leaking hydraulic fluid that is for the self leveling shocks, it is about a $1500 part new from the dealer. The hydraulic cylinders for the convertible top ALL eventually fail in these cars as well due to the seals corroding with age and the fluid leaks out - I have had already had to replace the ones in the front of the car over the windshield in the top of the pillars and it's likely the rear will need replacing soon as well as the car gets higher mileage as it's only at roughly 52k miles now. Nice thing though is I have a supercar that looks and runs amazing which originally cost over $130,000.00 USD new and it was purchased for a mere fraction of that from the original owner because of depreciation, at less than 10% of the original price actually. It runs and drives excellent no engine or transmission issues and the a/c works great plus it's a blast to drive and very fast & smooth on the highway where these cars really shine. The engine wiring harness was replaced though proactively as well because at the time of production in Germany they mandated automakers to use biodegradable materials from recycled plastic and rubber so the wiring harnesses in the mid 90's V12 Mercedes will eventually fall apart due to age and dry-rot which can cause electrical shorts and cause the engine to run very poor. This engine wiring harness connects to all the fuel injectors and also the engine throttle bodies. It is not because you have something wrong with your car or overheating ruining the hearness it is just a known issue with the SL600's and other V12's of that era so make sure to factor this in when you are buying one or don't know what's wrong with yours check the wiring harness on the top of the engine first! Enjoy! :)
