Your car doesn't need to refuel and change tyres? I doubt it. Also add insurance and taxes. And we're not talking about F1, just an entry level of GT4 series or the smallest Formulas season.Thats not so bad then. I only spend $100 a year on maintenance. Two oil changes.
So $10,000 a year. Every successful business owner in the world can start an F1 team then! We should have 40 cars on the grid no problem!
