Review of my experience at Speedway Ford.
My truck buying experience with Speedway Ford was excellent. .From beginning to end, my salesman, Eric Carter, was friendly, professional, and courteous. He asked the right questions to determine what I wanted and helped me find it. Neither he, nor Joel (the Sales Manager) was too pushy.
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.
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.

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.

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 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.
