untruthful advertising and sales

I would not waste my time with Campbell brothers Mt. Ogden Motors, they give USED CAR SALESMEN a BAD NAME! My son, starting out on his own, stationed at Hill AIR FORCE BASE, bought a truck from the Campbell brothers. They "showed" that the truck passed inspection. A 1/2 hour after he bought it, he filled the gas tank and it leaked all over the ground. The next day he took it into inspection and it requires 1500.00 to get it to pass inspection and 3200.00 to get it road ready. They won't give my son the inspection report that they had done TWO DAYS before he bought it. The inspection site shows the truck passing inspection when THEY brought it in, but failing when my son brought it in FIVE days later. How could that be? What is the connection between this dealership (dealers being key word) and the person who "passed" the truck. How many more have been ripped off from these guys. When I talk to them about getting the report, he just yells on the phone. People need to come forward and report.
