The car buying experience usually elicits a fair bit of
The car buying experience usually elicits a fair bit of anxiety from me, but I have to say 5 Star Subaru of Grapevine made my car purchase pretty painless. They are a business and they have to make money, I get that, but "Chief" (my sales consultant) was super easy going and I felt no hint of pushiness or pressure. We worked out a deal I was happy with and I drove away feeling good about it.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Bought a 2006 Mercery Milan here today. No pressure from salesman, just straight up great person. Arthur did let me ask the questions and answered every one. He didn't try to tell me a bunch of B.S. Just to get me to buy a car from them. Absolute great experience and professionalism.

We drove 5 hrs to this dealership to come look at a Chevy
We drove 5 hrs to this dealership to come look at a Chevy Traverse. Jenny Jo received us with a friendly attitude. At first, we didn’t make a deal due to the trade on value on our vehicle. Jenny suggested we try to sell our vehicle at a place she recommended. And that’s what we did. We came back and got the deal finalized. They were really patient and answered all our questions.

I had the pleasure of connecting with Hopper MotorPlex
I had the pleasure of connecting with Hopper MotorPlex last week after a friend had told me about them. Wow, while I’m a car guy, purchasing a daily driver is not my idea of having fun. The experience rein-instilled by faith in purchasing an automobile at a local dealer. Gary, Randy and the entire team were professional and brought a transparent and a no nonsense approach to my selection and purchase. Check out their impressive, clean and varied inventory….. you will be glad you did! Until next time!
