Behavior before my old man’s payment?

Hello, I have a question again to the experts I plan to buy an XC90. Probably I will go to the Volvo dealer and hope to get enough percentages there. Furthermore I want to take my current car (Saab Aero 9-3 Cabrio) in payment there. According to DAT this is still worth 18,000 How can it be needed to reach the DAT value? Specifically: – I have smaller paint racks on both fenders. Should I have this done before by the paint doctor, or not? – My aluminum on the front right has made a few curbs. Should I have the rim repaired? – Then there are still 2 smaller dents (only visible if you see very accurately) available. Should I also have this repaired? How happy is the happy thing about such things? Thank you in advance, Leif
