I have a couple off the top of my head.

81 Trek 410' bought for $25 sold for $150


73 Raleigh Record Ace bought for $24 sold for $256 on Ebay, and I kept the Brooks Pro that was on it.


84 Schwinn Le tour with maybe 100 miles on it. Paid $35 sold for $150. Buyer came to look at it, and said he wasn't planning to spend that much. But, he said he would because of the great shape it was in. Univega Gran Turismo bought for $25 sold for $100 without touching it. All other bikes I atleast cleaned up, but usually did a complete overhaul. The Univega sold a week after I got it without turning a single wrench on it. I have done pretty good on my fixed gear conversions I have sold (three so far), and made over $100 profit on each one. I spend more on them because each one gets a brand new flip/flop wheelset ($120 ebay special) and a new sealed BB.

The best money maker would definately have to be my two almost complete Paramounts (73 P13 and 76 P14) plus a box full of Campagnolo shifters, Brooks Pro, derailleurs, hubs, (two pairs of track two pairs road) pedals, 2 Cinelli steel track bars, Cinelli steel track stem, vintage steel adjustable Track stem, and a bunch of other parts for $330!! Problem is both bikes are my size and you will pry them from my cold dead hands!
