Great customer service.
Great customer service. Not pushy. Pleasant experience. Vehicle was as advertised. Would visit again if looking for a vehicle.
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Went to Mesquite Ford to upgrade my F-250 to a F-350 for towing a RV. Tom Carr was our salesman. He wasn’t pushy but was very helpful and not only found us a truck to do the job but the truck of our dreams! We’re so proud driving this vehicle and I love all the jealous looks from the other guys. Thanks Mesquite Ford! From your loyal customer
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!

Great experience!
Great experience! Fantastic dealership with a museum like feel. They took care of one minor problem I had with moisture in a headlight by replacing the headlight while I waited. Absolutely fantastic people, great service, quick paperwork turnaround.

Excellent Service all the way around.
Excellent Service all the way around. Maintenance was completed in a very timely manner. My initial appointment wasn't until 10:30 am. As I did not have any particular things going on so dropped it off at 8:30 am and told them that they could keep it as long as necessary. I received a call at 9:30 am stating that all maintenance had been completed, an our before my scheduled appointment.

The sales and finance staff were excellent.
The sales and finance staff were excellent. I have complete trust in their process. i am a buyer from south Louisiana, and they made it easier for me than if I would have purchased local. TAMIKA is a first class sales person, putting the customer first, and truly caring for the transaction. i would use them again in a heartbeat.
