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..

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!

I recently visited Tasha Buick dealership to check out a car that I viewed online. As soon as we arrived, someone was there opening the door for us to enter. The sales manager. Dillon greeted us and then turned us over to Sean to discuss the vehicle. Everyone was very courteous, and Sean was especially helpful explaining in detail information on the car with us and we ended up purchasing the Buick that day. Great dealership and it was nice not to have to deal with the pressure that we received while visiting other dealerships in Clearwater. I highly recommend this dealership. Their service is great.

Service dept is great. Been taking my vehicle there since I bought in 2020. Wouldn’t trust anyone else. Mike in service is awesome. Always listens, keeps me informed, explains things, open with all costs before any work is done, and does everything with a smile. Great people here. Would recommend to anyone.
