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.

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.

Josh was very knowledgeable and personable. He made the process quick and seamless as I knew exactly what I was looking for. The electronic paperwork was definitely an upgrade from a few years ago when it was all paper. Def a 10/10 experience.

Huge thanks to the sales staff for making this one of the easiest and most pleasant car-buying experiences I’ve ever had.

I started online and was pleasantly surprised by the responsiveness of their folks to text inquiries. They provided a few links to check out and generally showed my whatever I wanted. I started off wanting a used car but decided on new and they were flexible with proving me access to whichever years and trim levels they had available so I could make a decision on my own time. Very little pressure from my sales guy, Nick Scott. Very pleasant experience there and even going back to the dreaded finance guy was not a big deal. They were flexible around the times I could come in with my spouse to finish the deal and modified things in real time. Very accommodating. Good experience overall. I would recommend.

I recently purchased a vehicle from Titus-Will Chevrolet
I recently purchased a vehicle from Titus-Will Chevrolet Cadillac, and I couldn't be more satisfied with the entire experience. I would like to express my heartfelt gratitude to my salesman, Mario Reyna, who has now successfully helped me acquire two vehicles. Mario is an exceptional professional who genuinely understands his customers' unique needs and preferences. After deciding to downsize from our larger SUV to a more environmentally friendly option, we turned to Mario for assistance. We specifically sought a vehicle that offered both ample space and electric capabilities, and he expertly guided us through our options. After listening to our requirements, Mario recommended the Chevy EV Blazer, and it has proven to be an outstanding choice. My wife is absolutely thrilled with it and enjoys every aspect of driving the car, from its smooth handling to its impressive efficiency. What truly sets Mario apart is his commitment to customer satisfaction. He took the time to thoroughly research our needs, providing us with detailed information about various models and their features, which helped us make an informed decision. His dedication and keen attention to detail are truly commendable. I highly recommend that anyone in the market for a new vehicle visit Mario at Titus-Will Chevrolet Cadillac. His expertise and genuine care for his clients ensure that you will not be disappointed in your car-buying journey. Thank you, Mario, and the entire team at Titus-Will Chevrolet Cadillac, for making our car-buying experience so positive, enjoyable, and memorable. Your outstanding service has made a significant impact on our lives.
