Feldman Chevrolet of Highland

Sold me a damaged vehicle that was supposed to be certified. Went to go put running boards onto a 2016 Silverado I bought with only 35k miles on it only to see that the underbody where they attached was damaged, like the previous owner had running boards on but ripped them off and damaged the panel. Surely this was noticed during certified inspection but wasn't disclosed. I spoke with management and they won't even meet me half way on the repair.
