Well I can tell you, I just bought my car and found a few scratches on the car > Brand New, only had at the time 200 miles on it.
Anyway I made the dealer give me a we-owe you list, so far I got the entire front bummer repainted, looks really good, can't even tell. I go in on Nov to do the rest, they wanted to wait for the paint to cure before doing more work, they are also including a free complete detailing job.
I would be a major ass hole if they even put a minor scratch on my car inside or out. So it depends on you, mine is paid for and I still keep the plastic down on the floor mats.
Now we will see with the rest, so I would say, yes make him fix it.
Or he will pay even more in the future, karma man, it will come back on him it always does, you tell him that once. Unless he is a dumb ass he will pay to get it fixed.
