“I purchased a 2012 Gmc Sierra denali from stahl motors in monterey, ca in february of 2015. They are not willing to pay for the damages to my truck even though they sold me a completely dangerous vehicle, which I will explain. My truck didn't feel right as I was driving so I decided to take it to a shop to get looked at. There is a long list of things that is wrong with the vehicle, but I will mention just the main ones. The truck was sold to me without the rear brakes hooked up. The brake lines for the rear calipers were capped off by the rear differential. …”
