This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

They are so good they sold the car before i could put a deposit. Would definitely work with them again!
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

I've heard it said that buying a car is like having a tooth pulled without novicaine. Maybe at some dealerships, but not here. This was actually an enjoyable experience. Our salesperson was very knowledgeable about the car we were interested in and very pleasant to work with. No high pressure sales nor upselling of products or services.
141,000 SLT Still Going Strong
SLT with most options. Purchased at 127k. Currently have 141k after 17 months of ownership. The tranny that came with it was not original. I have had to replace ball joints, a/c condenser, brakes, wheels, radiator, a battery and a starter. Can't complain at this mileage. This is one of the quietest vehicles I have owned (that includes Audi A8's) and it's shod with Cooper Discover AT3's that chomp through snow like my Toro snow thrower. I also replaced the stock halogen bulbs with LED's and what a difference! The interior is comfortable, and I did replace the drivers seat bottom cushion. The nav system sucks, it's not very intuitive and it isn't very good at mapping the best route. Besides, I use my sedan for long trips. Phone integration is a breeze. Radio surprisingly decent. Everything works as it should. It's easy to pop the kayaks in the bed and the ebikes on a carrier and head out for the weekend. When moving stuff, I have the 80" bed so I can fit loads of stuff under the hard tonneau cover. The interior still has NO squeaks or rattles. Amazing. The heated seats are slow to heat, and the heated wheel is slow to warm up. But this thing is such a beast in the snow and rain I don't want to drive anything else! All in all a very reliable, well-built, and for the genre a good-looking vehicle. People tell me all the time what a nice looking truck I have. It's stock. Thanks, GMC.

Best car dealers we’ve worked with.
Best car dealers we’ve worked with. They are honest, genuinely kind, and stand by their product. Our son had an issue with a car he bought at Harbor City Auto Sales within a few weeks of buying it, and they put thousands of dollars into repairs without charging him a dime. Whenever I have a problem, I can call them and they’ll help me find a solution. If we’re in the market for a car, we don’t bother looking elsewhere. We love working with Harbor City Auto Sales!
