Excellent service, everyone answered all my questions. Mart�n Zavala is a great sales man, He told me he was a new salesman at that branch and he really did his job well. I would recommend buying cars from him.

Jeff Wiemann/CARMAX CY FAIR
My daughter bought a 2015 Kia Soul today from Jeff Wiemann at Carmax Cy Fair. 15 minutes into our visit she realized Jeff had been her salesman back in 2013 when she purchased her 'first' car! He's a great salesman- I have always given 5 star reviews to carmax- but Jeff deserves a huge 5 star review too!
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!

Let’s start off with what went bad.
Let’s start off with what went bad. I purchased a 2016 ‘Vette and less than 24 hours later the AC went out. To my dismay, I DID NOT purchase an extended warranty. Now, onto the rest of the experience. The team at Emmons Autoplex took complete care of me. They almost had to replace an entire AC system in order to fix the issue at no cost to me other than the time and gas it took to get there. The car was in immaculate physical condition, and was the cheapest C7 corvette within 100 miles. Kevin handled the no pressure, no hassle sale like a champ and the service team took care of the rest of the issues. The general manager even offered to completely scrub the deal if they could not complete the repairs. Overall, it was a great experience and instilled confidence in the organization as a whole on how they would handle business in the future. I would definitely purchase another vehicle from Emmons Autoplex.

I cannot recommend this location enough after the excellent service and very good experience I had with my first time financing a vehicle. Cesar Rodriguez and Raul Silva both worked with me to find a vehicle that suited my needs within my price range. These gentleman were extremely patient and professional when handling the sale. I would also like to thank Mark and Brandon in financial services. They both persisted through technical difficulties in order to deliver excellent customer service all the way to the end. I would absolutely recommend this location if you’re in the market for a used vehicle and I will be returning in the future!

GREAT SALES SERVICE
Bryon C. was amazing! We walked into the dealership looking for a Jeep that just happened to be sold the previous day. Bryon took the time to search all other dealerships to find one identical to the one we wanted. He was so helpful and had a great deal of patience with us during this entire process. Bryon continues to still answer our questions when we e-mail or call him. We have sent at least one other person to work with Bryon and we will definitely be sending more! We HIGHLY recommend Bryon C.! Thank you!
