Absolutely the best experience I’ve ever had car shopping. My wife and I had gone to multiple dealerships of several brands, but Blasius GMC stood out at the top. Both Edgar Allen Poe and Chris Prevosk were knowledgeable, friendly, courteous, and helpful. They answered every question and resolved any concerns. The process was extremely easy and stress free. I would absolutely recommend this dealership and duo to everyone! 10/10 all the way!

Mason was easy to work with and the process was very smooth and quick. We live almost 2 hours away so having it go so smoothly was a definite plus!

Absolutely love the vehicle that I got from them. It is used but it is in great condition compared to used vehicles offered at other places. The car salesman Alex and the sales manager Joey were great to work with. Both very easy going and they didn’t not pressure me. Joey was great about helping me finance the car at a payment I could afford. I’d buy a vehicle here again.

the buying process was the most seamless i’ve ever seen. as an entrepreneur time is everything. they took everything i gave them for what I was looking for and found the perfect deal. put me in a no brainer deal.

Very good dealership to work with, I just purchased my first car ever this Friday. The staff working there were extremely helpful in informing me on being a first time buyer & making sure I get the most for my money all the way to down to different insurance options.

The service department at Blasius is top shelf. They been helpful and honest in all the work with my truck in the past. I have been very happy with the times I have worked with them. I’ve also been very happy with the sales team. I recently traded in my old truck for a newer one. Mason, my salesperson is the man! He took great care of me and made the process very easy. Nick the manager and Joe in finance were also great to work with and made the experience work for my budget. Great dealership. I’m looking forward to a long working relationship with them!
