Thank you Matt, Spencer and James for your
Thank you Matt, Spencer and James for your professionalism and congeniality with the purchase of our Lexus rx 350. I must say it was the most pleasant experience I've ever had with a dealership. On the rating of 1-10 yours would be a 10 plus. Again, many thanks to you all. Faye and Dennis O'Connor
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

Always reliable and outstanding customer service.
Always reliable and outstanding customer service. Waiting area well stocked and comfortable. Staff friendly and informative, attentive to details and future needs. Service department used modern diagnostic equipment that can be reviewed while waiting
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Great team
Great bunch of kids - well, to me they are young. However - GA lost my title, then Nashville lost it so I still don't have a permanent car tag. That's been a harassment but I don't think it's on Car Max. I think some state workers are using COVID as an excuse to slack off.
