Karen, I believe her name was, was very helpful and friendly. Loved that gave the car a quick vacuum, wash and wipe down.

Huge shout out to Ron Moran, who made our whole car buying experience a breeze. He was so patient and honest with us throughout the whole process, and very knowledgeable. I never felt pressured or rushed. He took the time to go over all the details and features of my car. This was by far my best car buying experience. Thanks for everything, Ron!!

Everything was good with the service, but I found out a few days later that when they rotated my tires, they did not recalibrate the TPMS sensors. The front are registering as the rear and the rear is registering as the front. I live out of state and I will now have to find someone here in Texas to recalibrate the sensors.

Your service department has the worst customer service ever, they're not professional, and they basically ask you to take you car somewhere else! I paid over 3k for repairs, I went straight to emission testing and didn't pass. I called service right away, and they told me their warranty is for 10 miles only!! How come??? I paid $3600 for nothing!!! Victor Andrade was rude and he basically told me I will be charged again or take the car somewhere else!!!

Purchased a new used car from this dealership. The entire buying process was painless and quick. I was in and out in two in a half hours with financing secured and a payment that was within my budget. Staff experience was great from sales to financing. Really liked how I wasnt bombarded by staff when I got to the dealership and was given time and space to look at what was available. Will make future purchases from this dealership again when I am in the market for a new car.

My car had some pretty serious repairs needing to be addressed. Britt went above and beyond to accommodate me during a busy holiday weekend. He also ensured I had transportation during the time my car was in service. Last he communicated thoroughly regarding the repairs needed and the costs. Thank you so much for not just repairing my car, but ensuring I could continue my day with minimal disruptions!
