E90 Paint Repairs

Hello fellow fanatics

I hope this is in the right section - if not; apologies and please move.

I'm looking at closing a deal on an E90 320d tonight. But before I do I'm trying to get an idea regarding the feasibility and cost of some paint chip repairs and dents. The car doesn't look perfect and in fact some of the chips are fairly nasty.

I would be super appreciative if someone could give me an indication regarding how much (very ballpark, rather overstate than under) of the cost it would entail to repair them.

I have attached pictures below.

It's a private sale.
