Just a update regarding my last rating and review, after
Just a update regarding my last rating and review, after a meeting with the owner Ali Awada. He took care of me and paid for my car repair and gave me 100.00 for my family and I to have dinner. Thanks Colorado Auto Finders for doing your best to make things right for with me.

This is the second vehicle that I have purchased from
This is the second vehicle that I have purchased from this dealership and both times I have been very pleased with the price, the sales and finance department personnel and the overall level of professionalism of all involved.
Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

Thanks for your service James Hooker.
Thanks for your service James Hooker. Nice conversation about the sport of Parkour. I've never heard about that before. One word, two words, 25 words.
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.
