Used GMC cars for sale near Guadalupe, CA

I found a my SUV on Cars.com. Abe was our sales representative he was great definitely sending friends and family his way. The support staff was outstanding as well. We drove two hours away for a sold deal on a vehicle. Thanks again!

Jesús from the service dept and a young man from the Atascadero dealership helped me with the service of my car. Both were very attentive, helpful and knowledgeable. This was my 2nd time coming for service for my vehicle which I bought a little over a year. I was not disappointed, great service. Thank you!!!

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.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Great experience with salesman Josh. Very professional place, process of purchasing new Chevy Blazer EV was very smooth.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

Don't judge a dealer's service by the appearance of the facility. While well maintained, Mullahey's facility is definitely not one of the more impressive ones. Their service staff, however, is excellent. Courteous, knowledgeable and conscientious. There's a real neighborly feel to this dealership. I've found all the personnel go out of their way to show they're part of the community by showing respect and being courteous. The best Ford dealership I've ever experienced, and I've had multiple Ford products in multiple locations (Mustangs, Rangers, Explorers, in NorCal and Central Coast

I love this truck. It’s quiet and comfortable. The V6 has enough power for me. The options I got are convenient and make for a luxury car experience.

They follow up of my needs regarding buying a car. I would say they have really good customer service. I didn't buy a car yet from them, but I'll consider them on my next purchase.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

We recently purchased a vehicle here and want to applaud the wonderful service provided us by Landon, Raj and Michael. We were treated well and the experience was a welcomed improvement compared to our history of car purchases.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.
