More info on it? My guess is it's entry level, and $200 is a ridiculous asking price unless it's been upgraded with some nice components.
Of course, it's worth whatever you're willing to pay. To most regulars here, OFG and BBM are not off the mark. If you're looking for a functioning bike for utilitarian purposes, it may be worth $50-$100 - if it's functioning.
EDIT: Searched BF by using this string in Google: "Puch Pursuit site:bikeforums.net"
Came up with one thread, mentioning a Puch Mistal Pursuit. Unfortunately, the scans from the catalog were lost in a server crash. At least in '88 it was a mid-range bike (judging from the components listed in the thread), selling for $350 new.
