Bolivar Ford review
I selected a different car. Originally, I wanted a 2012 Chrysler 300. However, it was too old to finance without a huge down payment. So, instead, I bought a 2019 Cadillac XTS. I am very happy with my purchase! To boot, they even delivered it to my house! Nice!

Quest Auto Sales review
Very NICE dealership, huge selection of inventory, my credit isn't the best, but I got a nicer SUV than what I expected to get. I can't thank Scott enough.
2020 GMC Sierra 3500 review
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Cernohous Chevrolet, Inc.Reviews
Cernohous Chevrolet, Inc. review
The wrong transmission fluid was put in at the factory. We had to pay to have manufacturers mistake rectified, and have it changed. Cernohous gave us 20% discount on bill. We?ve bought many vehicles from them over the years. Easy to deal with. The Camaro has very low miles, 11,000. I?m hoping no damage has been done because of the factories mistake.

Reliable Chevrolet review
Great experience from start to finish - this dealership is quick to react, listens and addresses customer needs - that's what car buying should be! I will recommend Reliable Chevrolet to all friends & colleagues, and make sure they are my first call when it's time to upgrade/update any of my vehicles. Worth the trip if you're from out of town!

Earnest Auto SalesReviews
2020 GMC Sierra 3500 review
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.
