I can to this dealer just looking after searching online

I can to this dealer just looking after searching online and was met by Steph and worked with Connor. Connor is a great sales expert and working with everyone from Sean James Jordan, the whole team does incredible. Connor got me into a great payment and set me up with a great new ride for what I needed.

Third Purchase from Alicia!

Third Purchase from Alicia! Great experience as always. I wouldn't have it any other way. I'll continue to shop with Alicia and recommend her to everyone I know! I also want to shout out Jason for doing everything he can to make sure my purchase can happen.

Second time purchasing a vehicle from Brennan GMC &

Second time purchasing a vehicle from Brennan GMC & Buick. I highly recommend this team of experts. Jordan was so quick to explain all of the numbers and get me the best deal possible. He went above and beyond after his shift to explain all of the features of the car. Alicia was very friendly and prompt with all aspects of the sale. They really know how to treat their customers with the utmost professionalism and care. Thanks Brennan peeps!

I strongly advise against doing business with this

I strongly advise against doing business with this dealership under any circumstances. Our experience has been nothing short of a nightmare. After initial issues with our first purchase, we reluctantly gave them a second chance with a different salesperson but the same owners—and regretted it immediately. We were approved for a 2021 GMC truck that required repairs before signing. Since then, we have been subjected to endless delays and excuses for over three weeks. Promises of having the truck ready by certain dates were repeatedly broken, with explanations ranging from ordering parts to additional unexpected repairs. Each deadline was pushed back without transparency or accountability. When we were finally told the truck was ready for pickup, we were abruptly informed of a new issue—a stripped part—that would delay us another two days. The dealership admitted they had to absorb the cost of these repairs but showed no concern for the inconvenience caused to us, the customers. The sales manager’s behavior was unprofessional and dismissive, including referring to my husband as “bro” during a serious conversation. Since then, they have stopped returning our calls altogether. This level of disrespect, poor communication, and lack of integrity is unacceptable. If I could give zero stars, I would. Avoid this dealership at all costs.
