When I was a teenager, the family moved to Germany for some years. Immediately, my father bought a 2-year old BMW 3 series. 
The car broke down more than any other vehicle I've ever seen. 
He replaced a good portion of the parts on the thing. 
It got to the point where he considered renting a car to travel long distance. 
It was just a terrible car, but looked great.
Even today, I would never buy a BMW because of that experience.
