I wish my girlfriend's experience with a volvo had been as good as yours. a 91 740 sedan she bought new. Now has 140k miles on it. Electrical gremlins from the first week she bought the car. Relays blow, fuses blow, warning lights flicker. I've managed to fix a bit of faulty wiring that the dealer couldn't fix during 5 trips. A new transmission, starter, alternator, and water pump. The only thing that has gone right is that the pistons, rings, and cylinder heads are in excellent shape, everything else has been a terror. I'll take my MB any day.
PS: keep in mind thats in a dealer maintained car with near perfect service records.... whats a car without proper service look like?
