So, while debating a few items on the Challenge Supreme Court thread I had an idea for a future sub-class, the Raw Investment class. Basically it would be as if an investor handed you a check for $20XX to fund your project and those were the only funds you could use to build the car and prep it for race day. You can get as creative as you like with the money, no artificial recoup limit, but that check is all you have to work with. Here's the catch, no freebies, no exemptions. Everything you spend on the car is included in the budget, no free tires, brakes, fluids, tools, etc. If money leaves your wallet it's in budget. If you can sell something to recover money, it goes back into your project fund, no limits on recoup. However, unrelated transaction are still excluded from the accounting.
