Invoicing usage failure in combination with new car purchase

Hello, unfortunately, it has now also caught me or my vehicle and yesterday it was so coldly deformed that it is now completely over. I am not an expert, but the damage picture does not indicate that this vehicle will be repaired or can be repaired. I would have a question about the usage failure: suppose I now decide not to buy an available vehicle, but I order a new vehicle, delivery time eight months ate. How is such a thing billed? What do I have to do? I am in a happy position to continue to be mobile through other vehicles in the family circle. What if it wasn’t like this and I didn’t have access to another car? Greeting Tecci
