Foundation Chevrolet & Cadillac review
Foundation Cadillac did it again—and honestly, I’m not
Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

2021 GMC Sierra 2500 Denali review
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Country Truck & Auto review
Great experience
We purchased our Ford F350 about a month ago for a great price with absolutely no pressure or hassles from anybody there. They took our old F150 in trade and delivered the new truck down to Colorado Springs. Mike replaced the cracked windshield before delivery which we hadn't asked for or expected, which was awesome. Already put a hard 5,000 miles on it pulling a very heavy 5th wheel RV trailor in a across country move. The truck performed great and we absolutely love it!
