How can i make fast and easy money?

So i bought a car for 600 a few months ago. I got the whole "OH it runs GREAT!!" Well it turned out the cars alternator was dead and they must have used jumper cables so i could start it to get it home(Ford Probe..Now i no why people hate ford). Well 1000 later, im done! I want a new, reliable car (most likely BMW...good ol' german engineering) I have 1000 saved up still. Im lookin to buy a late 90's model in the 5-10 thousand range. Im already working a weekend job but i MIGHT have another job to work weekday mornings over summer.(knock on wood they havent called back yet.) So basically my question is...How can I make that 5-10 thousand by the end of summer (remeber im gonna sell my current car and im gonna sell it in the hood where theyll buy anything with wheels..im gonna ask 2500 hoping to get 2000 since i have put alot of money into it just to get it running) And NO i will NOT take online quizes sell drugs. become a man /stripper etc
