So many positives, except my battery purchase!
For the past 37+ years I have driven Cadillacs purchased from Lockhart! ALL SERVICE WORK has been performed at Lockhart, as well. I have always been pleased and continue to return to Lockhart for a car purchase and all service work! However, the last BATTERY I purchased from Lockhart failed after approx 11,000 miles and left me stranded last Friday. I expected better than 11,000 miles from a Lockhart purchase! I'm disappointed in the quality and performance of this battery!

We just purchased a new vehicle from Hare Chevrolet.
We just purchased a new vehicle from Hare Chevrolet. We worked with Reneau in sales, Ian and Mike from the management team as well as Bryan in finance. All three of them were professional and did their best to help us with our decision while keeping our best interest in mind. They weren’t trying to sell us - they wanted us to get the vehicle that best fit our needs. It didn’t feel like it was a one time purchase, it felt like they wanted to build a lasting relationship with us. Thank you!

This dealer is the bomb, I drove six hours to get to the dealership and the car that I drove to see was exactly how they described. Closed the deal within 1 hr. When I got home I looked for the wheel lock nut and it wasn’t there, went to dealer locally and bought one. Let unlimited motors know about the transaction and they refunded me for the part. Very, very satisfied with this dealershio

John P.
John P. and Zach M. work so hard to accommodate my family?s schedule with shuttles and getting our vehicle in and out quickly when needed. They recently facilitated a cracked windshield repair along with other routine maintenance the GMC needed. Hare truck and its technicians/mechanic?s have maintained and repaired my GMC Yukon that I purchased from Hare Chevrolet 8 years ago. Over 200K on this vehicle and going strong. Good pricing, dedicated professionals and easy to get to location.
