The dealership had a great selection of quality used
The dealership had a great selection of quality used cars, all well-maintained and reasonably priced. I appreciated their transparency and honesty throughout the process, including providing detailed vehicle history reports. The financing process was also seamless, offering several options and explaining everything clearly. I left feeling confident and satisfied with my purchase. Overall, I highly recommend Affinity Auto Sales to anyone looking for a reliable used car and a pleasant buying experience. Thank you to the entire team for making this such a positive experience!

One hour twenty minutes from walk in to drive off
This is the second car I've bought from CarMax (I also once sold a car). Every experience has been fantastic but this actually ranks as the best. Sales Consultant LaShinda John answered every question I had via email and then, for financing, by phone so that I walked in with the exact make, model and trim I wanted waiting for me to test drive and pre-approved for financing. The entire in-dealer experience took less than an hour and a half. Fantastic company and fantastic sales consultant.
