I was surprised at how well my 94 Isuzu Trooper does in the mud and snow. Haven't been stuck (well, seriously stuck) in it yet.
With gas at $2.45 a gallon, I'm happy to have a 91 Geo Metro as well. You know, the little 3 cylinder job? I do get laughed at a little trying to get in and out of it though. Don't think it was meant for 6' drivers.
