Well recently just purchased a 2012 Colorado reg cab z85 with the 3.7. If anyone here is familiar with the performance trucks forum I'm on there pretty often with my 2011 GMC Sierra with the 427 LSX and 106mm turbo. Anyways just introducing myself here and getting all the info I can on this truck as I know nothing outside of the full size LS world. Def a fun little truck I just got it tuned and gotta say it has surprised me how well it runs for a little I5. Gonna be V8 swapping it as well as doing the H3 interior and more then likely just keeping it as my little daily driver as my other truck is my race truck. Here are some pics of it at the dealer, 2012 36k miles with I think all the options you can get in a reg cab.
