BEST Auto Dealer in DFW
After spending 2 frustrating weeks looking for both a new Chevy Colorado and a Nissan Kicks - FINALLY found a HONEST dealership whom worked with me exactly the way car buying is intended to be. Long story short - the complete purchase from the time the Mark Itzo contacted me about a 2020 Nissan Kicks they had to the time my wife & I drove off the lot was UNDER 2 hours. & those 2 hours where incredibly wonderful with Mark treating my wife & myself as customers whom mattered to the finance folks whom had us in & out of the finance office in under 20mins. SO hat's off - cheers - two thumbs up - hugs - to ALL the staff @ N - orm Reeves Honda Superstore North Richland Hills - THIS Dealership deserves to be recognized as THE best dealership in the DFW area.

Kaiden, Anthony, and Nick went above and beyond to make
Kaiden, Anthony, and Nick went above and beyond to make buying my new Jeep Gladiator a smooth and stress-free experience. From the start, the entire process was handled over the phone and through text—quick, easy, and no pressure. By the time I arrived at the dealership, everything was ready to go. Kaiden greeted me with a friendly, professional attitude and made sure I was taken care of right away. Anthony worked his magic to get me top dollar for my trade-ins and locked in a fantastic deal on my new Gladiator. Then Nick made the financing process painless, explaining everything clearly and getting me in and out faster than I expected. I drove in from New Braunfels, and let me tell you—it was 100% worth the trip. The level of customer service I received was truly top-notch. These guys genuinely care about their customers and it shows. If you’re in the market for a Jeep or any vehicle, do yourself a favor and give them a call. AAA+++ service, highly recommend!
Nicest, best performing truck I've ever owned

Thank you Nick & A.W.E., in Plano Texas.
I had a 2018 all black challenger, and decided the color just wasn't for me. Nick Barbera gave me a smoking great deal on my trade in for a beautiful 2020 Challenger in indigo blue. It has a cinnamon red leather interior, and I am very happy with this car. Hats off to all the good people at Auto Web Expo in Plano Texas!!! I would recommend them to anyone looking to upgrade from the car they have, to the car of their dreams.
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!
