My wife was looking to purchase a newer Toyota 4Runner &
My wife was looking to purchase a newer Toyota 4Runner & trade-in her 2015 Toyota 4Runner SR5. She was really looking for a white 2023-2024 Toyota 4Runner Limited with low miles & sand/beige leather interior. On a Friday afternoon, she saw that Beaver Toyota had one on their lot, and we called them and told them that we were coming up to take a look at it (we live 3 hours away). Kelly said that she would have it ready up- front for us to view and test-drive upon arrival. We got there about 6:30pm & talked to Zack. We went on a test-drive, and he answered our questions. We went into the dealership and began the purchasing process. From the time we arrived to the time that we drove off the lot with our 2024 Toyota 4Runner Limited, the entire process only took a couple of hours. The Beaver Toyota Dealership is a state-of-the-art facility, and I look forward to using my "Beaver Benefits" that came with our purchase to help with the maintenance and longevity of our vehicle for years to come. If you're in the market for a new or used vehicle, I highly recommend Beaver Toyota!
This truck has a jerk when changing gears sometimes.

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!

My Beautiful Chrysler 200
After the horrifying wreck I thought I could never love another car like the last one. Then the fabulous sales staff at Carmax Kennesaw helped me find My beautiful Chrysler 200. She purrs like a kitten and handles like a dream. I couldn't be happier.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.

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!!!

My first time at this location and was a bit concerned b/c it was crowded however that is the norm and they are used to it. They handled the crowd with ease. They got me in and out. No complaints regarding my service rep, nor the job performed on my car. Will be returning for sure.
