Purchase a CPO 1.5 years ago and it had a clean record. Now while I'm in the process of upgrading and getting an estimate from Tesla for trade in, it show an accident that occurred a few months before I purchase and did not show on the CarFax. Are there any ground for things in my favor? Tesla is great and said they would adjust to a trade in price without the accident, but my point is that I don't think I would have purchased the car knowing it was on there. Also the trade in value is very low due to the influx of high mile CPOs so is it worth fighting to get a few grand more? Thoughts?
