I purchased this car new and I will give it one thing- it is a lot of fun to drive. However, I have invested nearly $8,000 in repairs in the last 4 years.(starter,gas tank,ball joints,ac compressor,suspension breakage, etc,etc). It is always garaged and has had to have a lot of body work because of rust problems. The dashboard looks like a lit Christmas tree! I've taken good care of this car, but just can't wait for another $1500 repair to occur. I will never buy another Mercedes- period. They're too expensive to repair. I've owed 3- Series BMW's that were more reliable.
It handles well and is just a fun car to drive.
Body integrity, ability to repair outside of the Mercedes dealership, cost of repair parts.
