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.

2015 GMC Sierra 1500 SLT review

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.

2015 GMC Sierra 1500 SLT review

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.

Sold a 2018 Honda Civic 2 dr coupe on Friday, 11/14. Alex was absolutely great. They purchased the automobile for exactly what they had quoted. We will never sell or purchase with any other dealership! They were fair and honest which is not true of many other dealerships. Would recommend whether buying or selling. Do not waste your time with anyone else.

Planet Lincoln review

The only place to buy a car.

From start to finish Planet Lincoln is a great place to buy a car. This is our second Lincoln purchased here and both times it was a great experience. No tricks or surprises, they do what they say and with friendly respect. Very comfortable showroom and facilities. I can't say enough good things about them. Thanks Planet Lincoln.

Thompson Motors Inc. review

Completely Satisfied.

Let’s start off by saying I really believe in buying locally. I have had the most pleasant buying experience from Thompson motors. By far the most professional in Oneonta. They have late model used cars at very fair prices. From today going forward I will always purchase from them. I have purchased elsewhere before and now I know what I have been missing. They will tell you the truth and help you with your buying decision. There was none of this running back and forth to the sales manager for approval. If you deal straight with them they will deal straight with you. I am sure they have a car or truck for anyone.
