Toyota of Richardson review

I’m looking and have been for a while.

I’m looking and have been for a while. I have found most car sells men don’t care what they say to sell a car. I was pleasantly impressed with a young man by the name of Luke Fox when showed me the cars and all that entails. When I make my final I hope I can buy it from Mr Fox. Thank you Luke

Auto Web Expo review

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!!!

Vandergriff Chevrolet review

Overall, Vandergriff Chevrolet service dept.

Overall, Vandergriff Chevrolet service dept. did an excellent job on my repair. With an extended warranty, the repairs cost nothing. But if I do critique anything, is the trying to get me to spend $1,200 in new battery cables. There was nothing wrong with them.

Freeman Buick GMC review

I was asked when I needed my truck back, I alex for 2pm.

I was asked when I needed my truck back, I alex for 2pm. I never got a call, and when I went to the dealership at 3pm because u didn't get a call back, I was told my recall was not done and it would be 45 minutes longer. Very disappointing the lack of communication. There service department was slow and I never got av return call. I was not able to wait so had to take my truck. I would continue to go to Ewing but they will not take the service plan I bought from freeman when I purchased my truck. Keep in mind we've purchased five trucks from freeman in the last two years.
