2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Working with Ethan on my 1st ever online purchase
Working with Ethan on my 1st ever online purchase - was the 1st experience everyone wants! He was efficient with communications, but never pushy. He was flexible and open to any questions, while walking me through the process! Friendly, knowledgeable, and great to work with. The financing process with David's help was a breeze! The process was time efficient and pretty flawless. He was on point with communication and very knowledgeable. Still loving my new car 2 months later- it exactly what I wanted and drives like a dream!!!
GLC43AMG

The experience was professional and painless.
The experience was professional and painless. The waiting room was clean and comfortable. I appreciated the quite efficient process. Restrooms were clean and well maintained.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

I was looking for a car and came across Brandon Tomes.
I was looking for a car and came across Brandon Tomes. I spoke with a kid named Ryan and he was awesome! I explained I was looking for a Mid-size SUV and was interested in the Volkswagen Atlas. He said he could vouch for this model because that is what he drove. He text me proof that he just wasn't saying this to grab a sale. I let him know I still needed to do more research and get my green in order and he was good and not pushy about trying to close a sale. I appreciated that more than I can say! It was refreshing not to be suffocated by a pushy salesperson!

I give 5+ stars to this dealership.
I give 5+ stars to this dealership. We accompanied our granddaughter to purchase her first car. Kim was the sales associate. She was awesome…no pressure, answered her questions, and helped her to get payments that were affordable. She found just the car that was best for her, with the help of Kim, at a competitive price. Everyone was so helpful and the finance department explained the paperwork in a way a first-time car buyer could understand. I definitely recommend Autos of Forney!

Best experience ever.
Best experience ever. Super helpful sales people making it possible to purchase our new Accord. The finance experience was excellent with everything explained to my understanding. My purchase at AutoNation was a friendly purchase and I wished I would have purchased our Ridgeline from AutoNation. I know I would have received a better deal at AutoNation.

AutoNation CDJR North Richland Hills performed an oil
AutoNation CDJR North Richland Hills performed an oil change and tire rotation and state inspection on my 2023 Ram 1500, July 25, 2025. The service reps all seem very professional. They offered me their shuttle service and had my truck done in about 2 1/2 hours. They did a great job! However, I noted that the tire rotation was not performed as per the manufacturer. All they did was move the fronts to the rear and the rears to the front. In accordance with the 2023 Ram 1500 owners manual the rear tires should have been crossed when bringing them to the front. The other noted issue I thought was huge safety issue, especially driving at night, was that for some reason the mechanic had turned my headlight switch to the off position. Turning that switch to the off position cancels every automatic function for your dash lights and center cluster (infotainment). By selecting the off position, ALL the dash and center infotainment lights go to FULL bright making it almost impossible to see anything outside the truck, especially with the 12 inch screen. It also prevents your steering wheel lights from coming on and prevents the high beams from functioning. I didn't know they had done this as I headed to work at 5 in the morning last Monday. I had pulled off the road twice on the way to work to try to troubleshoot the issue. It was useless because I couldn't see with the lights glaring in my eyes. I'm not sure why they had to mess with the headlight switch, but the least they could do is put the switch back where they found it. Would I recommend them to a friend, yes, BUT I'd warn them to verify their settings before needing them. And probably take it someplace else who knows how to rotate tires.
