This is the best dealership I have been to in years.
This is the best dealership I have been to in years.. They are Professional, honest, upfront pricing, no last minute bait and switch games.. If you are in the market for a vehicle, used or new, look at RIVARD BUICK GMC, Tampa, FL 33619 first. Even if you have to drive a little to get there..It's worth it..

Stephon was great to work with.
Stephon was great to work with. Made the purchase smooth and seamless. He had the truck pulled forward and detailed as we had much of the paperwork completed prior to going to the dealership.

I walked in out of the blue early Saturday morning.
I walked in out of the blue early Saturday morning. Christian came up to me and ended letting me drive a number of used and new cars. We didn't find one I liked so he searched the internet for me. Nothing was in there network that I cared for. Christian then got Dillon "the manager" involved. Dillon asked me about the car in the show room. I loved it. But No Way I could afford it. Dillon said give me a few minutes. 2 hrs later I drove off the show room floor with a 2025 Envision. Everybody envolved was terrific. Great job by all. I'll be back to Tasca in the future for sure.

Highly recommend Rivard GMC Buick.
Highly recommend Rivard GMC Buick. Haley was our sales consultant, and provided a no pressure, no games sales experience. Straight forward pricing, without all the money making add ons. Family owned business as well.

I worked with Jake Thompson and if there was any heavy lifting to do during the sales process, he did it. It was no doubt the easiest purchase of a car that I have ever made. Thanks Jake!

Malibu and the sale team were great.
Malibu and the sale team were great. Vehicle was in detail shop and waiting for us when we arrived. We were unsure of what color was right for us so Malibu parked the vehicles side by side for comparison and then stayed after working hours to close the deal. Thanks

Buying our vehicle at Kelley Buick GMC was a great
Buying our vehicle at Kelley Buick GMC was a great experience. Our Sales Consultant Braxton Nyland was waiting for us with the vehicle ready to test drive. We loved the vehicle and proceeded to the showroom to work out the details. To our surprise everything was up front and open, no exhausting back and forth. The General Sales Manager Brandon Wundrow also checked to make sure we had everything we needed and thanked us for our business! In no time our new vehicle was ready to drive off the lot!

I had an excellent experience at Kelley Buick GMC.
I had an excellent experience at Kelley Buick GMC. From start to finish, the team treated me with professionalism, honesty, and respect. They took the time to answer all my questions, walked me through every detail without pressure, and made sure I got exactly what I was looking for. A special thanks to Gustavo Sanchez and Russell Hernandez — both went above and beyond to make sure the entire process was smooth and stress-free. They were knowledgeable, patient, and genuinely cared about finding the best fit for me. The finance process was straightforward, the dealership was clean and welcoming, and I never once felt rushed or “sold.” If you’re looking for a dealership that values customer service and treats you right, Kelley Buick GMC is the place to go. I’ll definitely be back for my next vehicle.
