I really need to get a jack for my Suburban. I've never looked at later Chevy jacks, but the one for my '01 Dakota (and '97) was a scissor jack, with the lug wrench doubling as the crank handle. What I like about them is that the lug wrench and all the sections for the handle come in a decent, lined pouch. Stores neat, andthe lining keeps them from rattling.
Probably a king's ransom at the dealership though!
