Had a very good experience.
Had a very good experience. Julio, our salesperson, was very personable and didn’t pressure at all. If I had it to do again I probably wouldn’t have purchased the extended warranty. I did find a problem with the passenger side sun visor but we will see if they can help me out with it. I love the vehicle.
This truck has a jerk when changing gears sometimes.

Great used cars
Carmax has a wide variety of used cars to check out if you are not sure what you want. We found a 2018 Hyundai Sante Fe Sport with less than 8000 miles. Very nice vehicle that is roomy with lots of cool options. My sales agent was very nice, no pressure and we were in and out in less than 15 minutes to sign the paperwork. I would buy from Carmax again!
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.

I've dealt with better.
I've dealt with better. Not completely negative of an experience. Not the best either. Their service dept seems to be slacking. How do you put a car on a lot for sale with a check engine light on? I can see when it was last cleared. Not very long before I bought it. Salesman trying to tell me the engine isn't getting up to temp because it's cold outside. No. It's a bad thermostat. Headlight wasn't plugged in. And WAAAAY out of alignment. Their cars are supposedly looked over with a xx point safety check. I doubt that. Looked over, cleared codes, topped up fluids. Put an oil change sticker on the window. But did they really? It looks clean so I assume so. The detailers did a FANTASTIC job!! This car was super clean!!

747 miles for 21 year old truck
Jim Luttrell called me on a truck I was interested in when the sell fell through for previous buyers. Was already in Louisville looking at another. Took the chance to go look at it. Total 747 miles one way from my house. Easy process, glad he wore his mask. Bad thing....COLD weather!

YOU GUYS ROCK!!
I walked in and was immediately greeted. The guy that helped me had very great customer service skills and was very friendly. I have a crystler 300 and the oil needed changed and transmission fluid checked. I was expecting to pay around $250-300 bucks but got a discounted price and only paid $165. I definitely will be going back when service to my vehicle is needed again
