Been in the market for a new truck to replace my 2001 S-10. So I decided upon one of two trucks, a 2009 Colorado extended cab 4wd & a 2008 Silverado Reg Cab 4wd. I was very impressed with the Silverado. Nicely finished, very good interior, good power (5.3), and nice options. Only downside was the highway noise, 4 speed, and I still would like to see better mileage out of them (yes I know they are class leading). Next I drove the Colorado. I'll begin by saying that it is better than the 01 S-10, but after driving the Silverado, yikes. I drove the 4 cyl (not enough power for me), and the 5 cyl (VERY noisy), and decided I'd give up mileage & quietness for the extra power. The only thing the Colorado has going for it is the mileage, and thats only after GM improved it this year by about 11% (5 cyl). BUT, the price was more than the Silverado, and the Colorado doesn't come with Auto-trac, remote start or a sliding sun visor. I don't mind the looks of the Colorado, but the interior is pretty cheap. Although I was looking for gas mileage, I just can't justify buying a Colorado for more money than a Silverado (yes I know extended cab vs reg cab, but still.....). GM great job on the Silverado, but shame on you for the Colorado.
