The Colorado seemed promising when it replaced the S-10 in 2003. However, its unrefined five-cylinder engine, which it shares with its GMC Canyon twin, is anemic and doesn't offer a fuel-economy advantage over a V6. Notable shudder plagues the ride, the seats are uncomfortable and interior quality is lacking. However, handling is sound. Starting in 2009, the Colorado offered standard stability control. Test results for the Colorado also apply to the virtually identical GMC Canyon.
