Service dept 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.

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..

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!
