After doing hours of research on midsize pickups, I came
After doing hours of research on midsize pickups, I came to the conclusion that the Chevy Colorado ZR2 best fit my family?s and I. I compared vehicle prices across my state in Colorado and Stevinson Chevrolet of Lakewood hands down had the best price and inventory in the state. The staff and salesman were professional and very helpful. Stevinson definitely gave my wife and I the best experience buying a new vehicle we?ve ever experienced!

GREAT VALUE - GREAT SERVICE - GREAT TRUCK
HONEST Abe owns and runs this dealership and is not your stereotypical used car guy. He makes promises and keeps them. He took care of the finer elements of a used truck purchase by making sure everything worked and looked good before we took it home. He also referred me to his audio guy and assured that I received excellent service at an excellent price. I got more than a used truck with Truck Kings, I also got access to their network of trusted professionals to modify and maintain it. I will buy my next truck from Abe again.

The crew at AutoNation Chrysler Jeep West was genuinely
The crew at AutoNation Chrysler Jeep West was genuinely looking out for me while going through the tedious process of buying a vehicle. I was definitely sure of the vehicle that I wanted to help me in my day-to-day while also getting me out on the mountain roads for an adventure. Roberto saw what my needs were after my test drive to Mother Cabrini Shrine and he was able to work his magic while also incorporating Mo in on the final leg of purchasing the vehicle. I'm so grateful that I went there and that I got these two gentlemen to work with! They were incredibly efficient, all the while making sure I got the best out of my vehicle pricing and the vehicle itself!
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.
