LEAST favorite: the faded tape strip that the covertible top seals against. I bought the car after it had been sitting around for a couple of years (just 32 miles on it!) and that tape strip is now two-tone. I've tried EVERYTHING to even it up but NOTHING gets the job done. And I have access to a very wide variety of professional probucts from different manufacturers so I've basically given up.

MOST favorite part: the rest of the car.
