"I have owned more than a dozen MB products over the years and certainly they had their problems in the late 80's and early 90's. The latest S and SL class cars are light years ahead in quality and reliability. This SL55 is substantially better than even the earlier example of the lesser powered brother of just 3 years ago. Pricey but always a thrill to drive!"
"The MB SL500 is as good as it gets, in my opinion. The car is a style icon and the MB reliability and quality are well known. I have owned three SL's and all have been excellent.
If you opt for the SL600 (V12 version) you have more money than good sense. Priced at more than $40K over the SL500 you are literally paying that for 4 cylinders. I know, I have been there and done that."
"Biggest problem I have had is with tire pressure monitors-optional in 2003 and I wish the original owner had not selected this option. They have not worked properly since I bought the car, several trips to dealer under warranty with no results. Got tired of taking to the dealer. Later learned it will cost $350-400 per wheel to fix!! Would love to simply disable tpm but cannot. Its "illegal" even though tpm was not mandatory on 2003 models."
