What Owners are Saying About the 2003 GMC Sonoma Extended Cab

"For it's size, can't ask for a tougher truck."

"Purchased used. Have driven it for 15 yrs. For it's toy size, this little truck has out done the full size guys. Perfect driving, Handling, Hauling abilities. A little of a nuisance on fuel pumps, in my 15 years have had to have 4 replaced. 3rd door handle poorly designed, plastic is thin and I breaks regularly. Other then the above mentioned, this truck holds up to everything you could ask of it. It wasn't until around 240,000 miles that the tranny went, considering GM gives that tranny 130,000 to 180,000. So, giving this truck regular maintenance, gets you a few extra miles beyond factory design. You can't go wrong, especially with the ZR2 version! Love this truck. Won't part with it. Factory refurbished transmission, a few cosmetic touch ups and it's ready to go again!"

"Tiny & Tuff"

"My tiny truck is very reliable Gas milage phenomenal. Power is quite good considering that it boasts a. 4 cylinder engine and a mini powerhouse. Llow emissions&porty styling round out a stellar list of attributs that come together in a quality vehcble overall that's fun to e"
