With this in mind, please be careful who you get into bed with, so to speak. From bitter experience you need to make sure that you document everything you provide or place into the unit (tooling etc). Get it signed by all parties and write up an agreement amongst yourselves as to who is paying what at what point. Some people attempt to get their motoring aspirations paid for by other parties and then resort to illegal activity in an attempt to lay claim to cars, parts, tools etc. Please be wary and be careful.
