At Rogue Systems we generally source our spare parts from complete cars that are dismantled by us. They normally come to us in one of two ways: We import complete, roadworthy cars from Japan with light or cosmetic damage, or we buy in accident damaged cars from the UK. In almost all cases we have either driven the cars ourselves or spoken to the previous owner - often we have some history with the car. We provide pictures and descriptions of all of our donor cars, and should be able to tell you which vehicle a requested part has been removed from.
Parts are sold on a strictly secondhand basis. Unless otherwise stated they will simply have been removed from the car and - where applicable - cleaned; we do not offer a warranty of any kind on secondhand parts. That said, if we send you a part that is advertised as working (such as an electric aerial) and it is faulty upon arrival then we will happily refund or replace.
