Plain and simple: If you make money, they want some.
I have several businesses, a few trade names, and a few corporations, and they are all separate from one another. Most of those entities need to contract skills and abilities from other companies, so they all have costs to counter a lot of their profits.
Business startup and development is extremely common, so if you can't show a "markable" profit within the first two years of trying, no one will even question you. If your company goes away after a couple of years because it "just wasn't worth it", then no questions are asked.
Just make sure that the Ferrari is registered to someone else.
Jere.
