Buying CPO MY - Dent in Rear Quarter

Hi all - I have a deposit on a 2023 MY, particular spec/colour combo I've been waiting on for a while. Went to check it out over the weekend before making payment and there is a small dent on the rear quarter, a few inches back from the rear passenger door. I asked Tesla if they would repair this before collection, but they're saying it's 'within spec' due to being under 20mm.

It's going to bother me, to be honest. The car is Black, so will be very noticeable when clean - I've asked them for some pictures, so I can get some quotes/opinions of local PDR guys in my area.

Wondering if anyone has had anything similar removed effectively, without any major work (paint/filler etc)? I had a dent in my BMW 3 series in a similar place, which a few people I contacted wouldn't touch and said they couldn't remove. So I don't want to be in the same position with this car if I do go through with the sale!

Thoughts/advice appreciated - Cheers. (Will share an image here also when they send it through this morning)
