That is on the money and exactly right. Take it from an a hole who knows. Me.
Since 2015 I’ve literally lost track of how many new vehicles I’ve bought and subsequently traded in, some within weeks, none longer than a year and a half, every one traded in to a dealer in different states. In no instance did they even look at the vehicle other than to check the mileage. Couldn’t care less if it had scratches, wheel gouges, nothing. And in many instances I drove over a thousand miles to trade in, had a price in advance based on VIN and pics, and in every case the dealer paid me what they said they would.
Again, if you want to mod, do it for yourself, for your enjoyment, not for value. If paint chips, rock chips drive you nuts, get PPF. But five grand worth?
