I dont' think it looks that bad actually. Shave the rear bumper flat with the tailgate and that would help a lot. If it wasn't such a PITA to do, it would be better than a Colorado since you could tow/haul a hell of a lot more weight wise. Performance wise, Jesus, I wonder how much weight that removed?? That could well be a 3800 lb SS with all the seats, roof, and glass removed.
I would say shave more. Needs a Scotts hood. A lip up front. And damn can he drive it in the rain. I see where its rounded at the cab. Thought I saw glass but looks like too much rear window.
Agree with finish product, bed, and tail gate. I'm sure its AWD. Probably would be fun as hell to drive.
Image driving on our street. Strip everything and see how many people would ask what it is!
