I loved our experience with Antonio “Tone” Edwards at
I loved our experience with Antonio “Tone” Edwards at McDonough Hyundai. He was so awesome. Very informative and up front about the whole deal. We got a really great car and an opportunity to share some life with one another. I highly recommend asking for him if you are in the market for a Hyundai. We will be back.
Our 2021 Terrain SLT is really a nice auto.

Highly recommend this dealership!
Hands down the best car purchase experience I’ve ever had. A no pressure process and top-notch customer service! They really went above and beyond to make sure I was satisfied and taken care of.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

DriveTime Stone Mountain, Ga
I went into the dealership with very high hopes but very low expectations because I have some severe credit issues. Joseph Franklin greeted me at the door. He was very friendly and gave off a great vibe. During my appointment, people were pulling at him left and right from constant phone calls to in house interruptions. He handled every distraction with extreme patience and professionalism. Even though I couldn't get into the car that I had chosen online, Joseph showed me several options and made the process so pleasant. I walked out of there with a car that I really like and that suits my needs. Joseph is an awesome sales person and a definite asset to DriveTime.
Amazing SUV
I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

Easy to comprehend when on the website . Not too much words and letters to get stressed. Not hard to select your choice of car/truck/van...
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

Great Customer Service and Assistance
The salesman (Jerrel) was great to work with because he helped me while he was there Orr if he was off that day. He got me a car from another store then found out there were problems and found me a car around the same price range that was newer and less miles. Thanks for everything!

I was in the market for a new car for over a year now.
I was in the market for a new car for over a year now. It is nerve wrecking and overwhelming. Decide to buy a new or used. I researched, test drive, and contacted over 20 dealers for information. Until I finally found the perfect car for me at the perfect price, while on the CarMax website in Norcross, GA. A 2023 Nissan Pathfinder SV 4WD with 16,500 miles. Practically brand new and at least under $2,000 and the lowest miles from similar vehicles in my area. One great thing about CarMax is that I was able to scheduled the test drive 7 days in advance. They reserved the car for me, no worries about being sold before my test drive. Another great thing about CarMax is the price advertised is the price you pay. Other than tax, title and registration, no other “bogus” fees are added to the price. I only wish they offered special incentives/discounts like military, first responders, student, etc. But, I am extremely happy with my purchase!!! Shout out to salesman Young!!! He is the first person I spoke to; he got the car for my test drive, and in less than 1-2hrs I was on my way home with a new car!!! In other words, DO YOUR RESEARCH!!!
There are 20 matching cars close to your year range.
