I saw an RST the other day and the front end didn't grab me. I like the Silverado lettered grill but I wasn't sure about the Colorado. After seeing your pictures, I'm still not sure. I've got the exact same truck on my lot. I think I'll go stare at it some more until I decide. haha
I manage one of the largest Chevrolet dealerships in the country. If you're having problems with a dealer or have a question about something, I'd be happy to help.
