all joking aside, there's TONS of cheap, entry level racing that's affordable.
the one thing you'll notice though, is that the people that are racing-- that's their hobby. that's their laser pointed focus. that's their passion. they don't collect diecasts, they don't usually have a big stable full of cars or a flashy daily driver, they're not watching TV shows talking about if's n' butts, they're in the garage building, refining, researching, working on their car or the craft.
