Great Experience
After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.
Great Diesel truck when emission sensors work
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.

Always a pleasure to deal with.
Always a pleasure to deal with. They are fair and have full knowledge relating to all vehicles. All questions and concerns are taken care of immediately and professionally.
Great luxury ride with great pulling capabilities.
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.

Jason was upfront, honest and straight to the point. Didn?t play any games. I was offered a fair value for my trade in (unlike other dealerships). I was able to get my trade in and drive away in a brand new vehicle all under 3 hours.

Highly recommend
BAM didn?t have the inventory that I was looking for. They worked with me to help find me the truck I was looking for. They offered a policy that offers no deductible on my windshield. I was so happy with the hometown service I received and will gladly do this all over with BAM!

Everything went perfectly.
Everything went perfectly. From arrival to departure. I ordered a new Key FOB from the Parts Department, they called when it had arrived, made a WEB appointment, all very easy. I was greeted promptly and taken care of by very friendly people. When the job was done, I was helped to use my reward paints toward payment. The job was completed much faster than I had expected.
