1994 GS500 - Bought in '03 with ~30,000mi on it for $400.
I had the tank and tail plastics, just had them off trying to fix the carbs, which were FUBAR, along with bent handlebars, rusty everything, etc, etc....
Spent about a year of my spare time slowly buying parts and fixing it up, riding it all the while. Mangaged to turn it into a decent looker and sold it for $2,000 about two years after I bought it.
Of course, the guy I sold it to promptly tried to commit suicide with it.
Still not sure how he snapped both ends off my nice handlebars. Oh well. Cool bike.
