All German cars are over-engineered, when they get things right they get them really right, when they get them wrong, well...., just get a Honda if reliabilty is your goal.
Few years ago I rented a E-class Benz at Frankfurt airport at
Christmas time with 16 kilometers on it. Off-gassing from the seats was bad, rolled both back windows down, they stayed that way for two weeks driving around Germany in winter as neither were on their tracks.
