As an accountant, those investments would be hard for me to pass up. Anytime you can double, triple, or quadruple your money, you should definitely do it assuming the risks are not too high. If you have a reasonable chance at flipping either or both of these cars for that kind of profit with minimal risk, you should be all over both of them. Even if you are living paycheck to paycheck for a while, the profit far outweighs the costs. See if someone else would be willing to join you on the investment if you can’t afford it yourself.
