Earn some money. There are fortunes to be made by anyone willing to roll up their sleeves and work hard. Buy a lawn mower and mow 4 lawns per week. That should only take about 6 hours per week. That will easily afford you all the mods and tires you need. Onsite car detailing, window washing, boat polishing, etc. Lots of easy endeavors that young people don't do anymore that old people still want and will pay for. A kid with a paint brush and a bit of perseverance could buy a new Rubicon. Rather than identify wants with no money, look for ways to make some money. The rest will be easy. Earn money and buy some tools for starters. Don't put the cart before the horse.
