Shaun, have you thought about calling a few local dealers and asking them to keep their eyes peeled for any "interesting beaters" they get in on trade? Sometimes that can yield the results you're looking for... stuff they're not going to fix up and put on their lot... stuff they'll just wholesale to the low rent lots "on the other side of the tracks," so to speak.
Yikes... I didn't realize Penny Saver was nationwide...
