Best:
1984 Buick Century
1995 Nissan Altima 5 spd. (I only got stuck once but for 5 Min.)
1994 Buick Century (only had for a week then the transmission blew, but was just as good as the 84!)
1989 Buick Electra/Park Ave.
2003 Saturn Vue 2.2 5 spd w/ traction control (Current vehicle)
I have no worst vehicles yet!
Oh wait:
1988 Chevy Silverado 2wd (lowered with s-10 springs and cut leaf springs)
1989 GMC Crewcab Duelly (Had a solid 2000lb steel plate in the bed for traction.)
