“I’m writing here to state that the Cadillac with this VIN [XXX] IS A FRAUDULENT SALE my husband and I have experienced. The car show no damages on CarFax but when we took the car to a certified Cadillac dealership they said they were shocked we could even drive it. The catalytic Converter is completely missing along with several other computer systems issues. The car jumps up and down when you drive it, feels like horseback riding more than a car ride. Cadillac denied working on the car and advised us not to drive it at all Every single warning light that could be on the dash/odometer lit up approx 5mins of being on the highway. Throw the car in the junkyard where it belongs!”

THIS IS THE SECOND TIME THIS HAS HAPPENED.”
