Buying Bronco Sport
Miguel was awesome and very helpful! He answered all my questions and was very patient. I had a pleasant buying experience at 5 Star Ford in Lewisville, and definitely would recommend.

Overall review
Ruben was very polite, helpful and professional. He went above and beyond to help me. He even washed my truck before I left. He made sure that everything was taken care of before I left.

The salesman, Jason, was courteous, knowledgeable and low
The salesman, Jason, was courteous, knowledgeable and low pressure. We literally bought the car (2014 Mazda 3 I Sport) in only a little over an hour, including the test drive. No high pressure tactics nor “upselling”. I highly recommend Cransh as well as Jason B.

Fantastic experience.
Even in these trying times they made the whole experience easy and painless. From our sales agent Trent to the financial guru Brian, everyone was friendly and helpful. They are 96 miles from us and I would not hesitate to make the trip again if they have something I want. We'll worth the trip.

You don't find quick service like at McAndrews. So glad that DeMeon was my sales person! He answered all my questions and made sure all documentation was ready to go when I arrived. Was treated so nice. Thanks to Steve as well! First time customer. I will be doing years of business with this dealership. Thanks!

Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.

I left a google review bc overall I've been pleased with your body shop and service department! Love the popcorn, cookies, and snacks. I felt very welcome, wonderful dealership. I've always been a Sewell customer bc of their customer service, but y'all exceeded my expectations and now I want to be a life long Ewing customer. We had a few communication issues between the body shop and service dept the other day, but other than that, very happy! Thank you so much, to Tag and Dan!
