I was just curious to check out the inside of a spe vehicles—talk about unexpected! While waiting, I struck up a conversation with Justin from sales. I was just curious to check out the inside of a specific vehicle, but the battery was dead. Justin didn’t miss a beat—he got everything sorted quickly, and the next thing I knew, we were running numbers. I gave him my bottom-line figures—what I needed for the deal to even be possible. Honestly, I didn’t expect them to come anywhere close. But to my surprise, they made it happen exactly how I needed it to work. I even traded in the car that was in for the oil change! Justin and the team were incredibly easy to work with—no pressure, no games, just solid communication and follow-through. If you’re looking for a dealership that actually listens and makes the numbers work, this is the place. Highly recommend! More
