Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello! My name is Gary.Welcome to JustAnswer.I'm reviewing your question now, and will post back with a reply shortly.
I don't believe there is any way of knowing who was driving it other than a DNA test.
Have you confronted the service manager about this?
What was your vehicle at the dealer for, just a sevice, or some mechanical issue that may require roadtesting?
And the dealer has damaged the car, and they are not admitting to that either?
Do you need any further help?
I hope my advice has been of assistance to you.
