Revalued compensation and VAT

Hello, on the way to the Christmas holiday we had an accident with our 7 month old Dacia Lodgy, total damage. Since then I try to find out what the insurance paid to us. We have an extended new value damage, but at the Da direct they have only become aware of it when I pointed out to the clerk. In the meantime we signed a binding order for a Renault grand scenic, but it is smoked. Questions: Do I get the money that I actually paid for the Lodgy? (was a shopkeeper and therefore quite cheap) Or the money that he just costs new at Dacia? And what is the value of VAT? From what value (new replacement or residual value) is it deducted? Do I have a right to reimbursement, even if the dealer does not show VAT on the invoice? I hope for many answers that will help me!
