Owned a BMW. Had the audacity to use non-BMW windshield washer fluid. The fluid sensor broke; because in a BMW it’s a fancy sensor that is only compatible with specific washing fluids. Sums up my experience with that car. It was nice to sit in, though.
If you had bought a 7 or 5 Series at that time, you would not have had that experience. The 2001 7 Series had something like a 25% roadside breakdown rate.
So like... One in four cars would break down at the side of the road before it was otherwise EOL? One roadside breakdown every 800,000 miles or so? That really doesn't sound bad.
