In my locale, I would probably offer such a bike at around $125-150, but as a buyer, I wouldn't pay that much.
From a purist's perspective, there are "issues" with originality. (Modern seat, plastic pedals, replacement Schwinn chainring.) The lighted tank is a bonus, but the rest of the bike is pretty basic...a style not so uncommon in my area. Availability may be quite different where you're at and drive the price up.
