If that trash car is in the garage to be worked on, noone is going to care. If it is a trash car in the laneway that is being worked on and being kept in reasonable cosmetic condition, some are going to oppose it and some are going to accept it. Once you start collecting auto carcasses, leaving your property in disarray, and not doing much about it ... well, don't be surprised if people start viewing your property as an undesirable dump in the middle of a residential community. People have limits. While some people push those limits too far (in either direction), there are times when those limits are realistic.
