Why does everyone on WF give 2 shits anyways?
I do think the math is totally fucking wrong though like it was said above. Taxes and insurance are the 2 most fucking killer things in life when it comes to money ( if your American ).
I didn't read the blog post entirely, but I have bought websites, bought cars, etc, etc and any income this dudes gets will be taxed unless he has some shit set up where he is not American and a Ferrari will not be a business expense unless he tries to pull off that he has some "exotic" car wash or dealership he is setting up ( which still prob wont fly well ).
So if this person is somewhat successful already and is in the top federal tax bracket, and for benefit of the doubt, in a no tax state, then that $2k monthly revenue is going to be more like $1300 when done and said. I know there are some ways to reduce this, but this is just simple talk here. If they are in a tax state, well this could be taxed even more.
So with $1300 a month, he buys a Ferrari which will incur taxes, insurance, and ( trust me on this ) high/more freq. maintenance done to it then a new Honda/Ford. Pretty much every 3k miles is more then a "oil" change on these cars. Even on a lease, your gonna be out some coin just to drive it and have it in your driveway, let alone the gas and other costs for upkeep.
I think a more interesting story is how you keep ( and drive/have fun with ) a new-ish Ferrari with only $1300 a month income. Hell, lets just assume he kept the full $2k some how.. Still not going to be doable on that income ALONE and be driving it 2-3x a week very far.
