CarMax Live Oak review
Excellent experience
We bought a 2019Hyundai Elantra at this carmax. It was a very good experience. Staff was helpful but not pushy or aggressive. The fixed price was fair and made the process less stressful. The dealer charges were all reasonable with no ridiculous added charges. Overall an excellent experience.

Don’t let this small dealership fool you.
Don’t let this small dealership fool you. I purchased my car here and I had the best experience ever! Huge thanks to Alex, Eddie and Brian for making me feel like family. I will be back it if I’m ever in need of another vehicle. Keep up the great work guys!
2021 GMC Sierra 1500 SLT review
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.
There are 4 matching cars close to your year range.
