I used the Home Delivery service after visiting the website and narrowing down the car that I wanted from their inventory. The overall process was incredibly simple and stress-free. I choose a car that they would have to deliver from another state. They looked over the car I had chosen and warned me about a cigarette smell (which ended up being a deal-breaker). They presented me with a similar car as an option and we made an appointment for a test drive.
The thing about their home delivery service is that they bring the car to you for the test drive and If you decide to buy it, they have a mobile office with a notary and can take care of the entire transaction right there. They offer you a fixed price, which is great because you don't walk out wondering if you got the "best deal." Their pricing on cars and trade-ins seems to be pretty consistent with Kelley's Blue Book.
I decided to trade my old car in. They gave me a fair price and transferred my tags right there.
Overall, it was so much simpler than my last few experiences. I don't feel that I was taken advantage of in any way. There were absolutely no high-pressure sales techniques. No Upsells. No bait and switch. Everything played out exactly as promised by the website.
In addition, I did my due diligence about Carmax before contacting them. My neighborhood has a social media website, nextdoor.com. I queried about Carmax experiences with the local locations and got between 50 and 60 positive stories. (a huge response for the website). What was striking was that no one described any negative experiences. (Also a rarity for social media).
I would definitely recommend them and will likely use them again when it is time to replace my wife's car.
