Used 2023 GMC Sierra 1500 trucks for sale near Manchaca, TX

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

I bought a car from Olim. It was an out of state purchase and he made the whole process very easy and went above and beyond. 10/10 recommend!

Got 3 vehicles from this place. Awesome experience. The sales rep Daniel Pena and the finance guy Kyle Chaney did amazing job. Highly recommend Covert Buick GMC.

We were looking for a specific vehicle and found it on Cars.com. Sewell reached out immediately. I explained this was a purchase for my parents, who were use to driving around from dealer to dealer. I told my Mom and Dad there was an easier way. Will was our sales person and he reached out immediately providing me with all the vehicle info. We agreed to meet with him the next morning . When we arrived at Sewell, Will greeted us and was so friendly and kind. My parents were overwhelmed with the dignity and respect this dealership showed us even though my parent’s barely speak English. They have always been intimidated in high class places but they felt so welcomed- like family. Before you start thinking - Oh it’s because they bought a Rover… no they didn’t , they bought a used Chevy in pristine condition. The most impressive take away is that they didn’t treat us any less than their usual client base. They offered to wash the car and do an oil change and deliver it to her home the next day. All I can say is that Sewell Land Rover North Austin deserves to be recognized for excellent customer service and to thank Will for having the the most genuine care for us. I hope all dealers would learn from this dealership … It’s not always all about the money. I am positively certain the next time I look for a vehicle I won’t be going anywhere else.
