AutoNation Ford Littleton review
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.

Colorado Auto Finders review
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.
2018 GMC Sierra 1500 Denali review
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.
