Question about the scrap car’s verbatim declaration

Hello Have a short question and that is the following: I still have an old Mazda in the yard standing the transitory still is. Now it is so that I dare net in the 18 month period to get back there is more broken than I thought. Now I wanted to ask if I get mail from the registration office because the deadline has expired or net because I have the problem that the car is standing outside and net that I get worse because of environmental damage or something. I have to report there or mel the one after the course of the 18 months ?? greeting Mazdafreak
