"I will start with the disadvantage: very small trunk, just for golf clubs or a midsize suitcase.
Ok, now the advantages: the performance of a car this size with such a nice engine is incredible. Whoever says it sucks gas, it is not true. What do you expect with an eight cilinders, 5 liters engine? But the weight of the car compensates and makes it an affordable easy to drive car. If you want luxury and all the gadgets technology brings, this is the car for you. Reliable, excellent safety features, sound system, ventilated seats, push button for all comfort in long trips. What else can you ask for? I use it as an everyday car and I am having a hard time even thinking what car will be the next. Hardtop convertible, beautiful lines and eye catching.
Brakes are the best. hard to beat an SL with another car. If you go for a bmw 6 series, or a bentley, the size of those cars won't make them fuel efficient and ageless like the SL."
"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."
"I love this car, I bought it in January and it is a fun summer car.It is a eye catcher, where ever you go, people will tell you how much they like your car. It suppose to get 23 mpg on the highway but I got 26 doing 75-79.
What I don't like about it is for a car that cost what it cost new, bluetooth phone and satelite radio should have been standard equipment. My tire sensors were fine with bad tires but when I put all new tires on them, I've had nothing but problems with them when there is nothing wrong. I come to the conclusion that this is a rich mans car and a average guy can't afford the maintance."
