I purchased a Honda from Weir Canyon in 2018 and had such
I purchased a Honda from Weir Canyon in 2018 and had such a good experience that I always kept it in mind for my next car purchase. I came in last night to test drive the new Civic with Joe and was once again impressed by the sales staff here. There's absolutely no pressure from them to make a deal. Joe ran through his pitch, took everything I wanted into consideration and never made me feel intimidated or pressured to pull the trigger. After we made our deal, I worked with Eli on financing. I walked into his office reluctantly because financing is always the hard part of buying a car. Within seconds, Eli made me feel comfortable. He gave me excellent advice about what I might need and never tried to pressure me into purchasing anything I didn't want. I was in and out of the dealership within 2 hours and got a great deal. Most importantly, it was a great buying experience overall because I dealt with Joe and Eli. I don't plan to purchase another car anytime soon, but when the time comes I'll be back again and referring Weir Canyon to everyone in the meantime.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

My first time buying a car at Vista Motors, Mario is a great guy, super easy to talk to, I felt like talking to a close friend more than a car seller. He helped me to negotiate with the price that I want on the 2021 Jeep Wrangler Rubicon and he made it happened. The dealer forgot the key of the high lift jack and Mario drove to my house after work handed me the key. Very nice guy big thanks to Mario.

William truly does care; he listens and goes the extra mile to help and fix whatever he possibly can- we've been dealing with Will since 2017 and wouldn't want it any other way- he's the best- HE is the reason why we stay at GMC. -Salvador and Priscilla Elias
