A 2 car family and wife doesn't drive much so drove about 3k per year. Problems began after warranty expired. Over the years Had to replace Ignition wiring, fuel pump, key lock that required replace steering wheel & air bags, cylinder head, ignition wiring harness. This should not happen to a Mercedes. Maintaining car expensive (is that what they mean by luxury car.Had much fewer problems with my Celica. 2nd car now Infinity.
Car handles beautifully and comfortable on long rides. Drove twice to Florida from Maryland and did not tire after hours on road
Pay as much attention to producing car as done to design
