Great service center and staff.
Great service center and staff. I've bent working with the same guys (Sergio and Eric) for the last 10 years and they have always gone over a beyond in helping me with my car issues and give very honest opinions. Highly recommended
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Elvin Martinez excellent salesman.
Elvin Martinez was the salesman that took care of my business with Toyota of Richardson. He is very nice and helpful with everything that needed to be done. He also speaks perceft Spanish and English. My recommendation goes to him 100%.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

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!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

OUT OF STATE BUYER
OUT OF STATE BUYER I wasn't searching to buy a car. My fiance and I were having a general conversation about what car I wanted. Next, he sends me the ad of my dream car that really was something I thought would stay a dream. I fell in love. Being out of state I didn't realize how easy this process would go. I checked BBC Motorsports out and did my research. Google map street view, BBB (A+ no complaints), Facebook..Yelp etc.. I searched under every rock trying to locate anything negative. The reviews were so perfect. I initially didn't read them bc I did not want them to influence my due diligence. I came up with nothing! Buyers I wasted my time bc this dealership is 1000% legit. PROs Jasen is the best! Giorge is amazing! They are both PATIENT (I know I tested them and I wasnt the easiest customer) Beat my credit union rate where I've been a customer for 25+yrs by working with their lender Chase Answered every phone call, email and text(yes I communicated through all 3) Reviews are real(they were so perfect so I initially ignored them) Assisted me with a suggestion to use an independent mechanic to inspect the car being that I'm located in FL and I was unable to test drive the car before buying (Auto Critic was a plus) Sent me the carfax. Sent video and pictures. Shipped and delivered my car to Fl. Oh yea the CAR! The buying experience was so perfect and professional that I almost forgot to mention the Great Porsche I purchased. Low miles, clean, and a beauty well maintained and practically new for a great price. (No negotiating needed, the car was priced fair) The universe lined up this situation for me. It started as a dream, to a discussion and Jasen and George turned it into a reality. If you have doubts rest assured and TRUST! I ASSURE you they are the real deal. Seems too perfect to be true but IT IS!! CONs My credit union totally wasted my time. My paranoia all for no reason. Buy with BBC Motorsports! This is how buying a car should be. THANK YOU Giorge and special THANKS to Jasen! You both were amazing! I OWN A PORSCHE!!!! I OWN A PORSCHE!!!!

I HIGHLY recommend Five Star Ford!
I have been in the process of shopping for my new F-150 for a few months now. I was pretty set on exactly what I wanted, and the discounts that were applied did not leave a ton of room for negotiation. What my purchase ultimately came down to was the level of service that I was provided. Being a long time sales manager myself, I take customer experience very seriously. One of the dealerships that I was working with lost my business completely by not respecting my time, and ultimately providing what I would call a terrible experience. From the moment I began working with Pete Restivo, I knew that I wanted to make my purchase with him, and do business with Five Star Ford. Each time I stopped by, I was treated well by everyone that I interacted with, my time was considered, I never felt pushed to make the purchase, only supported in getting all the facts to make the decision. I do not leave a lot of reviews, and take it seriously when I do and I would absolutely recommend Pete Restivo and Five Star Ford to anyone interested in checking out a new Ford.

We had a straightforward, no hassle, seamless car buying
We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!
