Most fun: the Box
Prettiest: Cherry Red 1985 Camaro with an '80 big block Corvette V8 454. Was a beast!
Most reliable: 1998 Dodge Neon...yep, that's right

owned it for 13 years now and almost 200k miles later, just broke down on me a few weeks ago for the first time(fuel pump). Been well maintained and...just...keeps...going!
Worst: Geo Metro...enough said, lol!!!
