This is my 3rd car that I've purchased at Jim Glover Chevrolet. The customer service is great, friendly and helpful. I went to get my brakes replece, but Andy said my brakes are okay. I appreciate the honesty of the employees. Most places try to take advantage of women. But not at Jim Glover Chevrolet, they're truthful, respectful, and helpful. Thank you Jim Glover Chevrolet.

I had a great out of state car buying experience at Suburban Chevrolet in Claremore, OK. Allen Marrs made me feel very comfortable from the first phone call. He offered to hold the car until I was able to get there. He gave an accurate description and everything was as promised. Everyone is very friendly and helpful. The car is so nice I may never have to buy another, but if I do I’ll shop Suburban Chevrolet!

Excellent experience from out of state!
I am not a fan of working with dealers, however this dealership has given me renewed hope! I had a 5-star experience! I was searching the country (I live in Colorado) for the right combination of price, miles, bluebook value, etc and found what I wanted at Don Thornton in Tulsa. I purchased the vehicle sight unseen. Zach Brown, the sales rep, was phenomenal to work with, I highly recommend him! He made the buying experience from out of state easy! He provided everything I needed to make the transaction seamless. He was honest, forthright, responsive, and friendly...They picked me up at the Tulsa airport, brought me to the dealership, and had me on the road in less than one hour. The car was meticulously detailed and ready to go. Everyone I worked with at the dealership were great! Thank you!
