I'd like to take my Porsche on some rallies and Cannonball Run starts in my home city this year (if it happens). The entry fee is $25,000 USD which seems insane to me, that's 1/3 of my annual salary, I could never afford that. Are there companies that would want to put their branding on my car to pay for my entry fee? How does that kind of thing work? I welcome any suggestions, thanks a lot.
