Reviewed by mrasgreenDecember 08, 2025

My experience with this dealership was disappointing and confusing. After a week of communication, a completed credit application, and an approval for financing, the dealership abruptly refunded my deposit and informed me they would no longer sell me the vehicle. At no point was I disrespectful or unwilling to move forward — I simply asked for clarity on added fees and requested the agreed-upon paperwork. Instead of answering, management canceled the deal without explanation. I have purchased many vehicles and have never experienced a dealership terminate a transaction after approving financing and a deposit. I’m sharing this so other customers know to get everything in writing early in the process. I was fully prepared to purchase the vehicle at the requested price, and the sudden cancellation was unexpected and disappointing.

Dealer Response

At Diamond Buick GMC, we are upfront and transparent in the way we conduct business. We are a family-owned and operated dealership, and we work hard to provide a fair and respectful experience for every customer. In this situation, the expectations for the transaction continued to change. Those expectations did not align with our standards or processes. Because of that, management made the decision to refund the deposit and discontinue the sale. We stand behind our team and how the matter was handled. We wish you the very best in your continued vehicle search.
