Dealer Review:

We are located in Steamboat Springs and saw a 2017 GMC on a used GMC website. We called Angie. She was able to quote us that day what we could get the truck for and even gave us a value for our trade-in when we texted her pictures. Angie texted a sales quote with the final figures. We went down to Brighton a couple of days later and finished the sale. Angie spent a lot of time going through all the bells and whistles the truck had. We were so pleased and completely enjoyed working with her. I recommend Angie for any of your car/truck needs!

We recently purchased a new car from Valley Subaru. It was absolutely the best buying experience we have ever had. Jack Murtagh was terrific in answering all my questions and getting me what I wanted. I checked online for prices at all Colorado dealers and Valley Subaru beat the others by thousands. Even when we ended up on a factory order to get exactly what I wanted they had the best price. Well worth the drive from Colorado Springs to Longmont.
