Least favorite: Trying to squeeze into it while it is parked in my garage or in a tight parking spot. The stereo is weak as well. I wish it had an AUX jack so I could plug in my Zune instead of having to use a lame FM transmitter.

Most favorite: The sounds of the car (mufflers have just the right amount of growl IMHO), the style, and performance and handling (the other other "sporty" car I had was a 1987 Chevy Camaro with a V6 and the the XF is a far better ride).
