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.

Excellent Customer Service
Parker was our service associate and he able to get our Mini repaired for just our deductible with our extended warranty company. He is always professional and handles our needs with a calm sense of urgency. We will continue to use BMW of Dallas moving forward.

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.

Purchased a 2020 Toyota Sienna van in September 2024.
Purchased a 2020 Toyota Sienna van in September 2024. Could NOT have been happier with this dealer. 1. I am an out-of-state buyer (Kentucky). Every 4 or 5 years I buy a later model used vehicle from Florida or Texas. Classic Chevrolet has been one of the best experiences to date. They picked me up at the DFW airport (they are 10 minutes away) and had me on the road in an hour. The paperwork can take time (not their fault - Texas takes a lot of time to process the title) but the 60 day temporary Texas tag means you can use the vehicle why you wait. And Texas does NOT collect sales tax for out of state buyers, you pay at your state when you get the title. NICE. 2. Easily the LOWEST dealer fees of ANY on-line seller as I shopped and got prices. Some dealers wanted close to $2,000 over advertised price, Classic's fees were about $500. SUPER reasonable. 3. The vehicle was in fantastic condition. Their used car prep was super. They even sent me on my way with a full tank of gas. 4. This is a HUGE Chevrolet dealer. As a Kentuckian, where we build Corvettes, I think I counted over 15 in stock NEW Corvettes in the sales area where I was processing my purchase. Apart from the Bowling Green plant, I have never seen so many new Corvettes in one place. 5. The staff were super friendly. Big shout out to Thomas Payne my sales guy. Retired army Master Sergeant. Had a great conversation while waiting for the business department to process my paperwork. Thank you for your service Thomas and for being such a gracious sales person. I highly recommend this seller, and would buy another vehicle from them if they had what I wanted.
Great vehicle
This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

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!

Worth the drive!
The Ft Worth Sewell dealership had the best deal on a new F Sport with the options I wanted. Aaron Summerhill was a straight shooter and the deal went off flawlessly. The smoothest car deal I’ve ever had. I’ll be seeing him again when I’m due for a new one!

Saftey was their main concern
I called on the Pre-Owned vehicle I was interested in and dealt with Presley Wickham, the salesperson and Scott Miller, the General Sales Manager. I explained I was very interested in the truck but did not feel comfortable leaving my house as I have recently had surgery. Long story short, they completed EVERY aspect of my deal online and over the phone and email. Presley showed up to my house in a mask and gloves and we did business on the tailgate of the truck by signing the paperwork. The truck was immaculate on the inside and I can tell it had been totally sanitized. I cannot stress to this dealership my gratitude of taking such good care of me and being so mindful of being careful during COVID-19. Thanks again Presley and Scott at Town East Ford...I am a customer for life. Aaron

Mini Cooper Repair - Mini of Dallas
Oscar Miranda took great care of me and his tech (unfortunately, I don't recall his name) went above and beyond to help me figure out a few things related to the Nav system and a long-term, irritating issue with my trunk partition. Will definitely go back.
