Corroded electrical connections. Water in the oil. Rusted rear chain. Stuck brakes. Stuck cables. It could be a nightmare of fixing lots of little bits. New chain, new cables, brake bits, all those things will add up fast. A definite bargaining chip, but if you don't have another $200 or $300 to burn after the purchase price, it may not be a good deal for you.
