GMC pickup with awesome back door options to open wide.

2008 GMC Sierra 1500 SLT

Runs nice, seats are comfortable but not as cushiony as the higher end trucks. The air and heat are not great, could be colder and hotter. I have tried charging the ac system and still runs not as cold as it should. I love the back doors and how they open all the way flat with the truck. It makes it much easier to put groceries or anything in the backseat, especially if the car next to you is too close. Very comfortable riding vehicle but it seems to like to run right at 70mph. It is hard not to speed in it so I do use my cruise a lot. Love the Sirius music on the radio DVD player.

I would certainly purchase this track again and probably will.

2008 GMC Sierra 1500 SLT

I have never had any major problems with this vehicle I have never had any major problems with this vehicle the biggest problem I did have was changing the air compressor otherwise it is been a solid and dependable pickup truck. Other than the routine maintenance oil changes tires battery I have had one front disc brake job but otherwise it has been a perfect vehicle.

- William S

Very reliable with all the features of a 4 wheel drive and comforts of a sedan.

2008 GMC Sierra 1500 SLT

Problems. At 80,000 miles had valves go out and was a costly repair. . Performance. Pulls my camper very nice. Rides like a car. Drives very nice. Reliability. Would take this pickup cross country with 150,000 miles on it now. Comfort and features. Rides so nice. Seats are very comfortable. All terrain package with two tone leather is very attractive and durable.

- Daniel A

Dependable and hardworking GMC!

2008 GMC Sierra 1500 SLT

Excellent truck for work, hunting, off-roading. Has been very dependable. Most issues are from longevity. Older vehicles require a lot of maintenance. It has been extremely reliable. I drive my truck everywhere for work and personal use. It has updated features from the previous owner like a great stereo and sound system.

- A C

Great truck for daily drivers or for those needing a dependable work truck!

2008 GMC Sierra 1500 SLT

Dependable truck, low maintenance, rusts easily on the underside is the downside. Towing capacity is great for the size. I can easily tow a bumper pull horse trailer fully loaded. Overall it is a great truck that is very comfortable and I would buy a newer model in the future.
