I've also sued a Ford dealership back in 2016 for doing something similar. They dragged a tool across my hood and tried to claim the damage was done before it arrived. But, I always take a detailed video in the dealership parking lot before I turn the keys over to the service advisor to document any issues with the car. This car in question was a limited edition 50th Anniversary Mustang with 29 miles on it (#17 of 1964). I still own it, and it has 64 miles on it presently. It is being time capsuled for resale in the next 20 years or so. I brought it in to address an electrical issue with the center gauge cluster lights not working.
They fixed the car, but when it came back out there was an 8 inch long deep scratch in the center front of the hood. The service manager said, "Yeah, that was there when it arrived. I made comment about it as they were loading it up on the rack." So, I showed him the video I took in his parking lot a few minutes before. It was a 4k video that clearly showed no damage on the hood. "That's not your car sir." But, as he kept watching, I even included the limited number plaque, etc. So, I asked what they were going to do to fix it. "It was already there sir."
So, I marched into the general manager's office. Told him what was going on and he said he would get to the bottom of it. He agreed to repair the hood... which, meant after the body shop looked it over, would require a respray. This is no good for me as I was storing the car as a factory original collector car... and I was not about to get a respray. I wanted them to bring in a specialist to blend/repair the damage to maintain the originality of the hood. They didn't want to do that because Ford wouldn't cover it.
Soooo....
I ended up taking them to court. I didn't go small claims. I used the discovery process to identify who damaged the car, found out about the lie told to the foreman, who later covered for him with the Service Manager, who then admitted to telling the GM how the damage occurred. That tech lost his job, as did the foreman and the service manager. The dealership paid to have a specialist flown in from California to do the concourse paint repair, and they paid for my attorney's fees.
The moral of the story is, don't mess with my cars. I have plenty of free time on my hands to legislate any major issues... and especially, don't mess with my collector vehicles. I am a lot more lax with my road cars, like my Hellcat... but on the 50th and my 67 GT500... the degree of anal retentiveness I have is a serious character flaw.
