Payment possibilities after accident

Hello, short to the accident: When waiting at a traffic light, a car drove up and delayed me to the two cars standing in front of me.The report contains the following data: Repair costs without VAT 16.293,06 EUR incl. VAT 19.388,74 EUR Merchantial impairment 1.100 EUR Repair duration 15 working days Replacement value without VAT 22.100,84 incl. VAT 26.300,00 EUR Comparable driving points are mainly offered with regular tax. VAT 11.350,00 EUR Replacement period 10 working days Usage failure class H 65,00 EUR/day Would be nice if you could answer the following questions about the report. Is a fictitious billing possible with the data? Does the car then have to be repaired or is it also possible to sell to the residual value buyer indicated in the report? Is it correct that I receive the impairment only after repair? A repair period is indicated with 15 working days. If actually repaired, isn’t it? Is there a loss of use for Saturday and Sunday for the repair period, then a total of 21 days? Alternatively, a settlement to the replacement value less residual value is possible, isn’t it? Can I sell the car at the remaining value indicated in the report directly after I have obtained my opinion and have to wait until the opposing insurance company registers? The replacement period is indicated at 10 working days. Does it look like Saturday and Sunday? In what period of time does another car have to be purchased (e.g. within half a year)? I am happy about every answer. Greetings Sunshine1981
