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.
