Freddie was great…There were a few bumps along the way, but everything worked out and we now have our 2019 Tahoe
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.
