My salesman, Dave, was outstanding from the very beginning of the contact and sale. I believed he was honest and represented the company well. He and I agreed on a price over the phone, and I accepted it. Before the purchase was completed, I was engaged by another dealer with a lower price. However, I chose to stay with Dave because of his integrity and my belief that a deal is a deal.

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

I had an amazing car buying experience with Sam at John
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!

I purchased a 2025 Trax from Ginn Chevrolet.
I purchased a 2025 Trax from Ginn Chevrolet. My sales person Charlie was patient and knowledgeable. He invited me to test drive the vehicle and was quiet during the ride, which allowed me to listen for any unusual noises. During my time at the dealership, all employees acknowledged my presence and worked to earn my business.

Everyone there from reception to sales and finance were
Everyone there from reception to sales and finance were so welcoming and helpful. Seong was the kindest and patient through every part of the process. He was accommodating with my circumstances and made sure that I walked out of there happy. I then got to meet Kevin from finance. He was super kind and made sure I had everything I needed before I walked out of the building. I can't recommend this team enough. I love my Bronco!
