[McLaren-TAG]

I'd worry more about getting the car fixed right and documenting the repairs being done right more than being dinged with a carfax hit. The car is going to retain its value if the hit is as minor as you say and it's meticulously repaired.

An honest seller with the appropriate documentation is more valuable (IMO) than a clean carfax accident history. They're all old cars now, they're mostly going to have something.
