Great Buying Experience
I just purchased a new Toyota Tacoma today and was beyond pleased with the experience. I used the Costco Auto Program and was contacted by Ruben Puente quickly. He provided me the Costco price (which was great btw) and provided me trade in figures quickly via email. This was super helpful as I leave 2 hours away and wanted to make sure all the numbers were buttoned up before I made the trip down. Unfortunately Ruben was off today but answered his cell phone and arranged for his peer Lee Makarwich to help me when I arrived. They coordinated well and Lee had the Tacoma cleaned up and ready for me to check out upon my arrival. Lee went to bat for me with a discrepancy with the value of one of my trade ins and made sure I got the deal I was expecting. He was very professional and took great care to make sure everything was explained properly and that I was taken care of. Kevin Tran, the Finance Manager, listened to my needs and offered a great solution for my long term ownership satisfaction. We settled on a short term/high mileage warranty and gap protection to protect me from any unforeseen expenses that may occur in the future. He was friendly, professional and a pleasure dealing with. Overall from the being to the end, this was a wonderful experience and highly recommend checking out the great staff at Toyota of Fort Worth for any automobile purchase.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Zevar will make the process so easy
Two experiences selling a car here in the last few years and got a quick, VERY fair price for our used cars. Ask for Zevar. He is super fast, professional and personable. You won’t regret it.
Amazing SUV
I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

I work with Elio.
I work with Elio. An awesome individual. Very responsive to all my concerns. Made sure I was completely satisfied. I will go back to them in a heartbeat.
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

Overall great experience!
Had a great experience from start to finish with CPO Department at Huffines. Clear and timely communication leading up the sale and a short, direct purchase process. We noted a few minor items after the sale and the team was very responsive and helpful in getting all items resolved. I would definitely consider purchasing from Huffines again!

I am Very happy with the service I received from
I am Very happy with the service I received from Vandergriff Acura Arlington on May 1, 2024. George Hardwick went over and above helping me do an oil change on my 2020 Alfa Romero. He was very pleasant and efficient. He is one of the reasons my wife and I purchased this Alfa Romero and 3 other car from this dealership over the years.
