New and used 2025 GMC Sierra 1500 trucks for sale near Discovery Bay, CA

They were extremely accommodating. I was under a time constraint. They worked very quickly and efficiently to get the paperwork done so I could make my other commitment. I never felt pressured to buy the vehicle. I was treated great.

The experience with both the salesmens Martin Huerta and Hector Fimbres and Sales Manager Josu� Arenas, was excellent. This is the second vehicle I went thru the purchase process and they made it easy. Now, I definitely have to mention that the finance process and the waiting time to finally sign paperwork it?s ridiculous long. Besides that, everything else it?s great!

We were handled professionally and would return. The salesman was aware of what features were important to us and insured that the car we purchased had all of them and more.

Good experience from start to finish. Showed me exactly what I asked for without tacking on a bunch of extras before showing me final price.

I?ve always had a good experience at Marty?s GMC. The Sales Consultant, Corey Amara was professional, knowledgeable, and very helpful in my new vehicle purchase.

He is an excellent salesman who always treats his customers with kindness and respect. He listens carefully and helps us find exactly what they need without any pressure. His positive attitude and professionalism make him stand out in every sale he makes.

Tom Anderson and the service department at Henry Brown always do a stellar job for my Yukon. I've been going here 8 years and each time I receive friendly, thorough, and transparent assistance. Joe Stenz is stellar and makes getting my truck serviced a breeze. I was able to work with Wes recently while Joe was out, and I recieved the same help I've come to appreciate from Henry Brown which is a testament to how Tom runs his department. I highly recommend visiting Henry Brown for all your needs.

We love our new Yukon thanks for all your help!! Very fast, and helpful staff, appreciate everything!!! Carolina was very nice and very helpful and made our buying experience amazing!!

This is my 2nd vehicle purchase from Seguin Chevrolet. I will continue to keep coming back here and especially to my salesman Arnold Guerra. He is the best and goes above and beyond for his customers. If anyone is in need for a vehicle come to Seguin Chevrolet and ask for Arnold Guerra. The whole Seguin Dealership treats you good and like family.

I always use Williamson to service my trucks and they always do a great job. Erik in service is a credit to Williamson. I have purchased 4 vehicles from Williamson. 3 GMC Sierra?s and a Buick.

Basel is very knowledgeable, customer oriented and professional. Fast service and excellent experience. Clean waiting area.

Manny was a wonderful salesman. He was professional, friendly and helpful in getting us a deal on a used Jeep Grand Cherokee. Thank you Manny! You do your company a great service!

I just bought my GMC Canyon from Ed Morse GMC, and working with Juan Tabares was the best car-buying experience I’ve had. Juan was friendly, honest, and completely transparent — no pressure, no games, just straightforward answers and a smooth process. The whole team was welcoming and knowledgeable, and unlike many dealerships, there was none of that “pushy salesman” vibe. They focused on clarity, making sure I understood exactly what I was getting and that they understood what I wanted. If you’re shopping here, do yourself a favor and ask for Juan by name. He’s professional, efficient, and will make sure you leave happy.

Claudia Arredondo took care of me. I?m satisfied with the service work done on my vehicle. Thank you again for your service and look forward to visiting you in the future

Our experience at Mall of Georgia Mazda was from beginning to end a great success. Our salesman, Hykeem, was knowledgeable and helpful in finding the right car. The sales manager was congenial and not high pressure and we felt very fair in agreeing to a deal. Everyone we dealt with at the dealership was friendly and helpful in answering all our questions… and not having bought a car in 14 years our questions were many! We also observed them dealing with other customers in a similar manner.

Conan Thomas was my service advisor and the service was excellent. Took care of everything and made this service call as easy for me as possible. I will always go back to Sapaugh.

Selected them for service on my ford bronco sport it was quick and exceptional. It was outstanding from the to completion it was easy to schedule for my service.

Mo was incredibly helpful and efficient. I was treated with respect. I will buy from here again.

Good communication w/service rep (Mike C) car was ready and waiting at the time promised. I?ll certainly be back for any future service.

Trey and Remi were great to work with. They helped us find exactly what we were looking for!!
