Doesn't sound like you want to restore a bike yourself, so $100 isn't a good price if you have to put double or triple that (parts and labor) into it before it is a safe, good riding bike .. the newest Auto Mini is going to be around 40 years old (as Jur alluded to), steel, heavy, unwieldly/awkward fold, and probably with some rust issues... NY/NJ seems to have a fair bit of folder action through C/L, but you might also head into one of the bike shops that specialize in folders .. they might have something they've taken in trade that would be more suitable for your g/f and at a price that is less than trying to rehabilitate a bike that may be a can of worms and not really worth the effort once you're finished.
