I had a 2000 Z71 and was perfectly content with it until the SS came out in 03. The 6.0L, AWD, 20" tires and sportier suspension in a 1/2 ton truck made a hell of a lot of sense for what I really wanted in a truck. I kinda felt bad trading my old truck in because it only had 65K miles and was in great shape but that passed about 5 minutes after I left the dealer!
