I can say I enjoyed buying a car from Covert.
I can say I enjoyed buying a car from Covert. Starting with Jud, every person made me feel more than just a customer buying a car. Each staffer showed genuine interest in me getting what I wanted. I wasn't just a commission or one step closer to meeting the monthly sales goals. And, that is the best reason to buy a car from you. So, thank you.
This truck is the base model and that is exactly what we
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.

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.

Jason Brumpton was outstanding to work with. His communication was prompt, clear, and consistent from start to finish. He took the time to break down the service details in a way that made everything easy to understand, and he went above and beyond to help troubleshoot when necessary.

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.

We left our house this morning on a mission to look at 5
We left our house this morning on a mission to look at 5 dealership with basically the same style trucks and packages, just different add ons or colors. Reineke Ford was the first stop. From the second I hit the lot I had a comfortable feeling. We weren't swamped or ganged up on walking the lot. I walked in and asked for the online sales manager who paired me up with a sales representative named Melissa Kia and I was extremely impressed. Her knowledge of Ford trucks and how to operate all the tech and features was spot on. She answered all my questions and showed me every inch and feature in about 15min and already had it by the front door with a tag on it waiting. Prior to this, I had a lifetime of GMC trucks and a recent past with a couple of Rams. Both brands had failed with either an engine rebuild or a transmission so I was ready for something different. She sold me on the features and had me very interested. After the drive I met JB Brentson to put our deal together. We're both hard working parents but given the past few 10 years or so, we've had some life happens kind of things so we knew it would take some help. When our preferred lender Capitol One refused the offer they told us to make, we decided it was time to leave. JB asked me to trust him and give him a chance. He'd make it work. So we did because I truly felt this was going to be the dealership to make it work. So I abandoned the other choices and after about 20min we were signing the papers and shaking hands. It was absolutely refreshing to actually find a dealership that was there for us. The entire building staff talked to our autistic son and offered our kids drinks and snacks like we were family and I greatly appreciate it. Thank you "Kish" and JB for your support and help! Y'all definitely made a friend in us!

I recently had the pleasure of working with Denise, she is fantastic, who truly went above & beyond to help me find my dream truck, a GLE-63s. She never pressured me or tried to upsell me on something I didn't want. Instead, they focused on finding the perfect truck for me. Thanks to their expertise and dedication, I drove off the lot with my dream GLE-63s. I couldn't be happier with the entire experience and highly recommend Mercedes Benz of Laredo to anyone in the market for a new vehicle. Their exceptional customer service and commitment to finding the right fit make them a true asset to the dealership.
