The experience with Leanna Tabora was great.
The experience with Leanna Tabora was great. She helped me from my initial request on the vehicle and walked me through the trade in perfectly. Given that I was in San Diego, I was not sure how the trade would work out but everyone and dealer followed through with their commitment. Oscar with Finance was great got me in out within about 20 minutes. The entire transaction took about an hour and a half from when I arrived with my trade in vehicle.

Fast, Friendly, and Helpful
I saw a 2014 Silverado LTZ that had all the features I had been looking for. I set my mind to drive up and look at the truck (I opted not to transfer as I had family in the area I intended to visit). The hold process is GREAT. It's a quick click and I knew the vehicle was going to be there after I drove the 3 hours to look at it. I worked with Chris Biggs and he was great. We talked options on the truck and for financing (they beat my credit union's offer). He was incredibly friendly to be around and my wife and I thoroughly enjoyed talking to him as we waited on our financing offers. He was thorough in making sure we had all the facts and options. If I had anyone in the area looking to buy, I would send them to Chris in a heartbeat. Then I know they'd have a good experience and be completely taken care of.

I would highly recommend this dealership, specifically the sales person who helped me, Charlie. He was communicative, attentive and patient (not pushy) with me throughout the shopping and decision making process. He shared with me how he has been with this dealer for over 20 years and shared some of the reasons why he remains loyal to this dealer. And I can see that quality and a good customer experience matters.

It was worth the drive from Silverthorne to remedy a situation with a used Lexus GX460 that I acquired from WCG. The sales personnel were helpful, courteous, and professional and instilled confidence in me to return for future product and to refer anybody to go there for new or used vehicles and service. Ryan in sales and manager Derek got it done promptly which ended up being a faulty tire causing vibration at high speed. Also an honorable mention to Raul! Thank you all. I enjoyed the return drive to Silverthorne.
