It's all about packages & preferences between Chevy & GMC. It was my intention to buy a Colorado in 2015, but ended up with a Canyon due to fender design, wheel choices, and interior color availability (Cocoa Dune). At the time, Chevy didn't offer a tan leather interior, I didn't care for any of their wheel choices, and I preferred the GMC's grille and fenders to the Chevy's. This is GMs way of appealing to everyone, and I was glad I was offered the choice. At the moment, with GMC's rebate appearing on the website, where Chevy's doesn't, the GMC appears to be the better deal when you're talking about a base model crew cab pickup. But things change when you start adding options. They're going to get their money one way or the other, it just depends on your personal tastes. This sort of brand engineering has provided quite a few laughs over the years, especially when I worked at a Pontiac/Olds/GMC dealership. We had customers who believed that the GMC pickups were built better. I just smiled & nodded.
