Above and Beyond!! Brendon Powell...
I had made a previous trip to Shottenkirk Toyota on September 12th and met with salesman, Brendon Powell. I had wanted to trade in a Nissan Titan and after discovering that truck had issues, Brendon had to tell me that they could not make a trade, it was tough on him but at least he was truthful. I made my next trip to Shottenkirk on September the 19th with another vehicle to trade in on a Toyota Tundra and I made appointment with Brendon Powell again. This was a good choice since he knew all the information from before. Brendon worked extremely hard to have the vehicle I had pick out work but with my previous new Titan hanging over me he was having issues making financials meeting my demand. Brendon continued to work on my case and brought in Danielle from finance to assist me, while Danielle was explaining me details she received a call, and said she had good news, a truck had arrived that was not listed and that truck would fit my budget!! I would like to commend both Brendon and Danielle because they listened and worked with me to find a truck that would fit my budget and my needs. I have been let down by Nissan with a lemon truck but Shottenkirk redeamed my faith in dealerships and I left with a new Tundra that without those two working together I would have never achieved.
This truck has a jerk when changing gears sometimes.

Awesome experience!!
I had a great first car buying experience here! Juan Gomez replied to my email promptly and set up a time for us to meet to test drive the car, and I fell in love with the car, so I bought it! I was nervous about being scammed because I don’t know much about cars, but I never felt like that at all. Juan was friendly, knowledgeable, and helpful, and helped us to get a great deal on the car. Financing was also a breeze and I once again did not feel like I was getting scammed at all. Dominic Hernandez helped us to get a great warranty and made sure to speak to my car-knowledge level. My dad said this was the easiest car buying experience he had, and while I have nothing to compare it to, I agree! Love Honda of Fort Worth and will definitely recommend to friends and hopefully return if I ever need a new car!

Highly recommend this place!
I entered and told the salesman, Anthony, that I was short on time and was looking for something reliable and fun to drive. He wasted no time setting me up for a test drive and was very knowledgeable about the cars I was checking out. Very personable guy who got me into a new Hyundai Elantra in the shortest car buying experience I have ever had. I would highly recommend these guys to everyone. Customer service was beyond expectation.

We traveled over 500 miles to purchase our vehicle from
We traveled over 500 miles to purchase our vehicle from Hiley Buick GMC of Fort Worth, and it was absolutely worth it! From start to finish, the entire staff was incredibly friendly and welcoming. Taylor, our salesman, was amazing?thorough, extremely knowledgeable about the vehicle, and professional while also making the process fun with his great sense of humor. He took the time to answer all our questions and, best of all, was never pushy, which made the experience stress-free. Ron in finance was also fantastic. He was professional, knowledgeable, and had a great sense of humor, making what can sometimes be the most stressful part of buying a car feel easy and enjoyable. The long trip was well worth it for such an exceptional experience. We highly recommend Hiley Buick GMC of Fort Worth to anyone looking for a great car-buying experience. The entire team is top-notch, and we couldn?t be happier with our 2025 Yukon!

Awesome help getting car repaired at low cost to m
I bought a used Chrysler 200 from them and did not buy the extended warranty. I just had the warranty that comes with used cars there. Anyway the alternator went out and the Chrysler computer needed reset. The car had to go to Chrysler for that repair. Pricilla was my service advisor and kept me up to date with everything going on with my car. Vandergriff also gave me a loaner car for 3 weeks while my car was being repaired. All I had to pay for was a new battery. I could not have been happier with thier service department.

I received an add on Facebook for Hiley GMC Buick of Ft Worth. I had been looking locally in Lubbock Texas. While looking at their on-line inventory, I noted that several models had fantastic discounts and rebates. I couldn't get anywhere near these advertised prices in Lubbock and the saving was more than enough to warrant a trip to look in person. Brenden was so helpful before the trip and accommodating in person. Long story made short; buy from. Hiley and ask for Brenden. They'll treat you right!

Five Star Ford--NRH & Jim Rich
I would HIGHLY recommend Five Star Ford in NRH and Jim Rich their Internet Sales Manager. I have been in the market for a new truck for a few months now. I have had a pretty good idea of what I wanted. I have been to many dealerships much closer to my home that treated me very poorly to say the least. From the first time I spoke to Jim on the phone till the second we drove off the lot, he was welcoming, nice and most importantly what he said was not changing like every other dealership I have been too. You can tell Jim is a true professional and cares about you and what he does. He wasn't trying to pressure you into things you didn't want, I can defiantly see why he has so many repeat customers. We ran into many others in the dealership that day and everyone was very friendly. I can't recommend this place and Jim Rich enough!!!! Thank you very much Five Star Ford of NRH!!!!!!!!!!!!
