Be bold.
Rust on the rear fender.
Cars been sitting for years so you know the vacuum lines and such are rot.
It's the typical car that kids see what it Could be, and not what it is. It is, frankly, a money pit.
[Stop here, if you don't get it I will, it's awesome, but get into the mood here, k?]
Now, this POS is taking up space, I need a hoby, so I'll tell you what, if you give me $500.00 I'll take that car off your hands and maybe use it to get me to school or something. Probably going to cost me every dime I make for the next 20 years, but heck, for $500 bucks you gain some space and help me out.
It's all in the approach. What's he gonna do, say No? Ok, great, then you are now negotiating and might snag it for a few hundred.
Be Bold. Be Imaginative. Everyone buys their first car, that process follows them their whole life, it defines you. It is the sum total of what you have learned do date.
So, whatcha got? Go get the car.
