Everything was handled at the Chevrolet showroom when I was there to purchase a top of the line Cadillac. 2. I was discouraged from inspecting the vehicle prior to signing the sales contract.

The TPMS is malfunctioning as a result of the dealer incorrectly installing the sensor at the time they replaced the factory wheels with the 24in wheels the vehicle was optioned with. 3. Sales person lacked product knowledge - he did not know whether the vehicle was equipped with a spare tire or had run-flat tires. He was also unaware of the headphones that were included with the entertainment package the vehicle was equipped with. More
