The Colorado I had was the I5, it had pretty good power a good amount of bottom end torque. It was in the shop several times the left rear door panelbroke and kept falling off, the dash was seperating at the firewall, under the dash rattled all day every day, and the front end ate up tires the factory tires lasted 5000 miles, the second set lasted about 6000 miles, third set about 6000 miles the fourth set had about 8000 and were wearing out too. During this it was at the shop for front end work which GM coud not repair. Chevy kept saying everything was fine.... you know how they are! Thank God I traded it in.
