Yeah, don't feel bad, you're not alone. Bought a mid 90s Cannondale M300 LE that wasn't even my size, everything on it was trashed except the seat post. :-P Freehub seized, cassette missing spacers, both derailleurs rusty and wacked, seized front hub, seized BB, and cantilever brake arm, snapped seat post binder lever, torn seat, rusted steel stem and handlebar, cracked Gripshifts, one brake lever snapped in half, and later discovered a big dent in the monostay of the frame, and the steel fork rusted under the bubbling paint. Paid $35 for this heartache. Never shop at night and where there isn't plenty of light present.
