Parts Cache
Go and get it, there is lots of value and profit that would cover the shop and car costs. Advertising ISNT expensive, how expensive is "free" lol.
If you have access to the $$ get it. The connections alone you make would be priceless. As mentioned organize, label, research. This all can be taken on(partly) by the young lad. Research for the most part is at everyone's fingertips.
Good luck.
