honestly id start an audio business. not just car audio first and foremost it would be about instuments, I would put guitar center to shame, they are horrible. but i would incorporate home audio car audio and instruments all into one place. and have people that actually know what they are talking about and try to offer the best prices and trade in values so people will choose my store to give their business to thus making up for selling things cheaper. to me its not so much about staying rich as much as just living comfortably and happily. 1 million dollars would last me my whole life and then some because i dont need stupid things that other people with lots of money buy.
