[pothole]

Fairly ridiculous list.

Only one Audi I can see, the A6, which isn't at all fun to drive. Nice car. But not fun. A 750Li is definitely more fun than a A6, but that's in the least fun list.

Anyway, the fact is, most people are pretty clueless about cars and these kinds of popularity lists are all the same - tenuous link to merit at best, often inversely proportion. Just observe the most popular films, music, TV shows, whatever. Mostly junk.
