I bought mine in February of 2009 with 11,000 miles. I used it as a daily driver for 3 years. Now I have 90K miles on it. So far, I have only replaced the aux air pump, one pulley bearing, and the intercooler pump. All are all common failures on these cars. That makes it one of the most trouble free cars I have owned. You will find this website is excellent for diagnosing a problem. Most importantly the car is a thrill to drive. However, I don't recommend it for the type person who will run to a Mercedes mechanic when something goes wrong unless they have plenty of money to waste.
