It's a simulator about buying cars. You can be richer, or poorer, you can have luck with cars that you find, or not, just like real life (thats what she said) The game uses RNG (fancy way of saying pick number 1 to infinite) to simulate car prices after buying them (you have a risk that the price either decreases or increases)
Please ignore the "Not enough cash" bug, I seriously dont know how to fix it Some cars cant even be bought so ignore this too. I will not update this anymore.
