I recently purchased a car.
I recently purchased a car. After about a month, I noticed some grinding in my rear passenger tire. I gave my salesman Chris (Toyota west used cars) a call and told him what was going on. While it was a simple fix, one I probably could’ve done myself if I would’ve looked better, Chris had me bring it back in and the dealership looked at the car and took care of it. This is a major reason I have purchased several cars from this dealership, including when they used to be Hatfield. They are always taking care of their customer. Thank you to my Toyota West used car salesman Chris! He was absolutely fantastic. I also wanna thank the management team for approving my car to be fixed. You all are the best. I’m so happy with my new to me 2024 Toyota Camry hybrid.
