Sal is an awesome sales agent, pleasure to work with. Not overbearing, very knowledgeable and friendly. With his Long Island accent I felt like I needed an interpreter at times. Lol Thanks for a great encounter

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..

just now New Excellent experience from initial visit to
just now New Excellent experience from initial visit to picking up my GM certified truck! Note we aren’t local to the area but live 97 miles south of the dealership. It was worth the trip 👍 I really appreciate how the team at Tasca listens to you rather than try to bulldoze you thru a canned process like most dealers. They were flexible and responsive to how I wanted to evaluate the vehicle I was interested in buying and my timeline. Have to give shout outs to so many individuals. Cassandra promptly responding to my internet inquiry, Dillon the sales manager setting up my first visit, Nolan my sales professional meeting me for the test drive then taking care of everything up to final delivery and Melvin the finance manager who made sure the money part went smoothly. I know there were others behind the scenes who am thankful for as well. Definitely recommend! Would definitely buy from them again. Worth the drive & time!!

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.

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!
