You did good for $140. The parts are muddled but this is a very fine frame. It looks like someone built this up from parts on hand to sell the bike. It is worth considerably more than what you paid for it even in the mid sized city where I live in the Midwest. I've picked up a number of bikes of this quality at $140 or less. I know I could get $250-$300 easily to sell; more if I was patient. In a large city, I'd peg the value closer to $400-$500.
