I was wondering what brand/make/model I should be looking for in vintage bicycles to buy, and potentially flip for a good re sale value. Apparently my vintage Nishiki wont go for a whole lot according to the guys in SS/FG area. I have a lot of money into and it is a truely beautiful machine. Fully revived with all new parts and powder coat. Schwins hold their value pretty well, eh? If anyone could post some helpful advice, it would be greatly appreciated.
