What Owners are Saying About the 2005 GMC Sierra 1500 Extended Cab

"No Better GM Truck Out There"

"These are by far the most reliable - used trucks you will find on the market. Don't buy an 07 or newer, too many mechanical and electrical problems. GM has never been the same since the 03-06 trucks. Ultra reliable, easy to get parts, timeless body style, great work horse. Crew cabs will pull 19-20 mpg on the highway no problem (with stock suspension/wheels)."

"Great vehicle"

"Very tough...very dependable !!! Never owned a better truck. This thing will pull anything and you won't even know it's back there."

"Unbelievalble reliability"

"It's a beautiful totally fabulous truck. 1500 HD SLT. Original cost $38,000 in 2002. I've towed my boat with ease for 24 years and my brake linings still have 50% left. Brakes have not been replaced. Unreal. Boat and trailer is at least 4500 lbs unloaded. The comfort is exquisit. At 110,000 miles, I replaced the alternator in 1 hour max, easy. Every possible accutrament within works like new. Just blown away after 23 years how new it looks and inside leather comfort is like new. I'm having the small dings removed, replacing the shadowed lights and making it look new. So easy. I love this truck!"
