Best of the Breed

2008 GMC Sierra 1500 SLT 4dr Extended Cab 4WD 6.5 ft. SB (5.3L 8cyl 4A)

I decided to replace my SUV with a full-size truck. Choice came down to an '08 Sierra SLT vs. an '07 Tundra Limited ('08 Tundra priced way out of my budget) because I've always bought Japanese. Tundra has nice powertrain but falls short in every other category, especially it's bloated price. GMC SLT's greatest selling point is its luxury grade interior. Tundra is very weak here. GMC's shift at any speed automatic 4x4 is far better than Tundra's crude hi/lo 4x4. GMC has better crash test scores than the Tundra. This is the 1st full-size truck I've ever owned but driving it is actually a joy. Parking is a learning experience but the parking assist makes it doable even for a newbie like myself.

I had been searching for a truck for a while and finally settled on this one. Picked up a used 2008 with 32000 miles and ive had it for over a month and absolutely love it. It rides sooooo smooth like a caddy and gas mileage is pretty good. Highway at 65mph is 23mpg. Toyota can't touch that. I have the 5.3. Haven't had it long enough to say how the reliability is, but i know from experience these 'Chevys' are so tough. I have the HD tow package and rear locking diff and it pulls my 20' Cobia like its not even back there... Interior is nice and tight. No rattles, no quirkiness. No engine rattle or cam bump. Sounds As if the motor is not even running. Truck is just pure quality!

I traded in my 02 Dodge about 1500 miles ago and I could not be happier. The truck performs great and will haul the snowmobile trailer much better than the Ram did. I am averaging roughly 15mpg which is 3mpg better than the Dodge.

I moved up from a 96 Chevy S10 to a 2008 Sierra, and like the title says so far so good?! I am impressed with the ride and overall appeal of the truck. I had a spray-on bedliner installed and the truck has no problem getting any big job done.

I traded my 2001 GMC 1/2 ton 2WD with 195K miles (it still was strong as heck)for this truck and love it. I have always had good luck and good service from GM trucks. I bought this one with only 25K miles on it. The 8cyl to 4cyl fuel management was a little awkward at first but it is systematic now. On the open interstate at 75mph I have averaged 18mpg+. I was surprised. I have towed a 27ft camper with it with ease. The seating is comfortable even on long drives. Two thumbs up !
