My experience was great.
My experience was great. The people were nice and helpful. I would recommend this dealer and would buy another car from them . Please go see the people at Boaz Chevrolet.
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.

I purchased a 2005 Corvette over the phone.
I purchased a 2005 Corvette over the phone. The car is in excellent shape low mileage and the experience of buying this vehicle was hassle free. Also had the car shipped to Las Vegas Nevada no problems. Would purchase another car from unique Auto again.
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.

Don't be fooled by just low prices - they all pay the same for vehicles. These guys know how to order new trucks with the right packages that won't cost you an extra arm and a leg. Save thousands by knowing how to order the right option packages on your next vehicle. Some dealers don't know how and you either get a truck with too many stupid options or not enough.
Really impressed with the performance
Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me

I'm posting my review on multiple rating sites.
I'm posting my review on multiple rating sites. This branch in Herrnstein in Waverly is wonderful. We had chosen a car via cars.com and decided to see this one. We drove 2 hours to get there, knowing that the truck listing might not be what we wanted Well the truck fit the bill, we set up financing easily, and we were on the road. Staff members stopped over to thank us for purchasing from the business. We highly recommend Hernnstein in Waverly. By the way, my review is legit. I did clip a photo of the listing.
Good power very comfortable ride
Good power plenty of room the truck has all kind of new technology in it that helps with driving safety and with job performance Awesome
