We bought a 2020 Ford Explorer in April our outstanding salesman was Thomas in used cars he took care of us above and beyond and we’re so grateful unfortunately we had issues in August and had to bring our vehicle in the first service technician was not so good kept telling us what they couldn’t do and nothing about what they could then i believe the best service technician stepped in an made this what we were thinking was going to be a nightmare a more pleasant experience and handled all of our issues thank you Thomas our salesman and Glen our service technician for giving us a piece of mind !!!! Thank you guys
So much better than prior GMC Yukon
I came to this car from a 2016 Yukon which was a rolling dumpster fire. At 102k miles, I haven’t had a single failure with this car. It tows extremely well, the seat comfort is by far the best I’ve ever owned, I don’t love the exterior styling, but its such a great owner experience that it doesn’t matter. Maintenance is like owning a Camry, cheap and infrequent. AWD system makes driving in all conditions a breeze. Great vehicle.

SIGN ON GATELIFT COVER.
QX 80 is very comfortable driving. Despite it's size, maintenance is great. Thieves often mistaken the rear gatelift cover to be something valuable hidden inside thereby forcing it open and causing damage. May be a sign may be necessary. The current look is nice but attractive to thieves who have no idea of what it is.

2013 Dodge Avenger
The buying process was long but at the end everything worked out in my absolute favor! I appreciate the amazing customer service and the help with the purchase of my very first car!!!
Luxurious beauty.
Most sturdy, luxurious and roomy car I have owned. I feel safe when driving this car, it is a very smooth ride and a noticeable eye catcher, boy am I blessed.I love the body style. The only kick back is the 3rd row leg room is a-little to short, my family have long legs, as long as they don't ride back there its wonderful.

From sales to finance to the person who delivered my vehicle to my house, excellent service, communication with professionalism and kindness. Afterwards, Patrick, my rep called me to see how I liked the car and how was it running. Would definitely recommend and buy from them again.

Great experience, would recommend
Great experience at CarMax Wichita! We worked with Sales Consultant Vernon Nelson and he was kind and helpful throughout the entire process. We felt zero pressure from him, which was a stark contrast to another dealership we were working with who pressured us hard and had an attitude when we didn't buy on the spot. Vernon just wanted us to have the best car for us, regardless of whether or not that was from CarMax. They offered us a fair price on both the trade-in and the vehicle purchase itself as well, so no we'd have no hesitations recommending them to others.
