I owned a couple of MBs back in the 80s and while they were reliable (boringly so), they were just not fun to drive. I recently purchased a 1999 E430 just because it looked good on the lot and had only 30000 miles on it (in June of 2007!). I must say these cars have come a long, long, way. This thing is powerful, smooth, and handles like it's on rails. It gets 31 mpg on the Interstate (in cruise control)and averages 25. If you need a great used car for a real bargain price, look at one of these wonderful machines.
Engine - powerful yet economical.
Cup holders are lousy. It looks like a company as competant as MB could make a great cupholder or two.
