Excellent service department
The service guy, name James was great. Had a problem with my breaks he took me back to the mechanic who was going to work on it. (Joe the mechanic)They both Gave me a thorough explanation of the problem, which I thought was unique. Of course, they could have told me anything like “ Hey you need a new Johnson rod” I would have probably said ok. It was my second visit to Gettle service overall excellent experience.

Great experience
Ayman Abouelsoud greeted my family and I as soon as we walked into the dealership. He was very pleasant and helpful with everything we needed. He understood and worked his magic to get us to stay within our budget and get a great vehicle. I would come back here to see him when we decide to purchase again. The dealership was clean and spacious. Sales team and finance were great too. I recommend Elder Ford of Tampa and specifically recommend Ayman to assist anyone.

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.

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..
