Overall we had a good experience.
Overall we had a good experience. Easy to schedule appointment. No pressure Test drive at length. No last minute Additional fees added. Unfortunately they had just received the car and it was snowing the days before therefore they were not able to pick up on some things like Cracked screen. They did offer discount in price but we felt it was not enough therefore deal did not go through. Kim kate was really helpful and friendly.
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.

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!
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.

Loved my whole experience at CARMAX, Fort Worth!
My brother-in-law recommended that I check out car max when needing to purchase a good used car. First I went on line to see what cars were available. I found exactly what I wanted, in my budget, at the Plano location. Luis Delatorre, my fabulous agent, at the Fort Worth, River Ranch Blvd., had the car transported to Fort Worth and I purchased it on sight! I Drove it around the block, and had all the paperwork efficiently delivered to me within 30 minutes! I've found my future dealership and will recommend Car Max to anyone who will listen to me!
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 drove over two hours to look at a new truck that was on
I drove over two hours to look at a new truck that was on a really impressive discount. After I arrived I was informed that all of the trucks with that discount had sold several days prior after I was told by multiple people that truck was there. I was then informed by the manager that it was a mess up on their end. At most dealerships that wouldve led me to leave however their salesman and the manager not only honored the discount on a different truck but put me in a newer, less miles, and better equipped model for a difference of maybe $800. While the mix up of what had sold versus what was available was frustrating. The fact that the salesman and manager worked with me to get me an even better deal speaks volumes. Also, no hidden add ons or xx was a huge plus!

Darren Shin -EXTREMELY knowledgeable Sales Advisor
We built/ordered 2024 GLC300 for my wife in May 2023. Took delivery on 12/1/2023. Darren Shin was our sales advisor. We moved our business from another Mercedes dealer because Darren was EXTREMELY knowledgeable about the Mercedes autos, options, process, timeline, etc. He did NOT use any pressure whatsoever. he focused on educating us to ensure the vehicle was EXACTLY what my wife wanted. If I had a sales opening in my firm, he is exactly the high performing sales person who I would hire!! Kudos and well done.

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!!!
