I drove the first Colorado in my area today. It was a CC long box Z71 in the metallic red color. The engine and transmission operated flawlessly. Rolling in the gas it seamlessly shifted when it should and accelerated exactly as it should. I never liked the old Colorado as it felt noisy, rough, loose and cheap. The new Colorado's feel like a slightly smaller Silverado. It is very quiet, tight, and the doors close nice and solid. When going a steady speed and stepping on it, it down shifts exactly like it should. True, it is not a v-8 but the v-6 revs nice and does NOT feel under powered what so ever. All I can say is WOW...very nice job GM!
