Binding order cancellation?

Hello, I ordered a new car on the 13th of April. At that time everything was also good financially and had no concerns. Now the car of my partner has a motor damage and had to urgently procure another car for them. Now I stand there to say without a buffer and a financing I really do not want. The vehicle is not yet built and there was also no information from the manufacturer as the stand is. Today I sent an e-mail to the car dealership. Now my question: Can I just get out of the contract, because this is not a sales contract, but only the order. What about the 15% payment of damages? Suppose the car is delivered (delivery period according to the car dealership 4 months to possibly one year), but I don’t buy it and don’t sign the sales contract. Is this possible? Everything came differently now as planned and a Neuwagenka If the vehicle is not even built, it shouldn’t be a big thing, right? Or can the dealer insist that the car is bought now and I have to take care of it from where I get the money? Would be nice if you could help, because I’m going through so slowly…
