Car expenses

Dear Sir/Madam,

As a self-employed student, I drive a lot of kilometres by car. I already enter the cost of petrol as indicated in the article on Dexxter. However, I have a question about other costs, such as insurance and car inspection.This car is registered in my father’s name. I therefore question whether this makes a difference when claiming other costs, insofar as these correspond to the professional use of the car based on the amount of kilometres. And if this is allowed, how do I enter this in my accounts? I do not have any invoices for these costs.

Thank you in advance.
