I have a 90 HP Schwinn as well. Got it about 8 years ago. Good condition for 70 if I remember correctly. The components work but 200GS are considered low low. Not a selling point at all. The real value is the full lugged, butted frame which is special painted and hand drizzled spider web like paint. Schwinn says” no two are alike”.
Built with nicer parts, it is a great platform for different styles of riding.
