I am thoroughly satisfied with Temecula Valley Buick
I am thoroughly satisfied with Temecula Valley Buick since I purchased my Encore GX in 2021. Always very personable and keep you informed as to how your service is progressing. William was my service technician today, and when my car was finished he walked me to my car and shook my hand before leaving. Nice gesture!! When my car needs service next time, that for sure will be my go to dealership.

I was wowed by the service I received from Lynn at
I was wowed by the service I received from Lynn at Hatfield Buick GMC. I have been looking for a car for a year and a half, been to 4 different dealerships in Los Angeles, and have left each time feeling scammed and disappointed without a car. Every trick in the book had been pulled on me. I finally decided to give buying a car another try. I found my dream car with all the bells and whistles I wanted 2 hours away from where I live at Hatfield Buick GMC. I talked to Kevin who got my pre-approval process going so they could hold the vehicle for me, then I headed out to the dealership a few days later to meet with Lynn. The process was smooth, Lynn was upfront and professional, and I was driving off the lot with my brand new car within a few hours! I could not be more pleased or shower more praise. I will be recommending Hatfield Buick GMC to everyone I know for a seamless and elevated car buying experience. Thank you Lynn, I really appreciate you and the entire team at Hatfield Buick GMC!
