Who am I to criticize what may be someone else's pride and joy? As the old saying goes, "Rubber Wheels Beat Rubber Heels".
The focus of a lot of the C&V members is on classic mid to top end derailleur bikes.
It's not necessarily snobbishness but bikes like yours where/are considered "gas pipe" department store kid's bikes, sold at a time when "10 Speed Racing Bike" was the buzzword and anything with 2 wheels, dropped handle bars and derailleurs qualified.
Ride and handling of better quality bikes are what many forum members value.
Also, from a maintenance and repair standpoint, getting a bike like yours tuned up to work properly but more importantly work SAFELY can more than exceed the cost of a better quality bike.
New brake blocks, cables and housings, tires, tubes, derailleur cables, plus the labor costs of servicing the bearings in the hubs, crank bottom bracket and headset could run well over $100 USD. If anything like a hub or wheel needs to be replaced then add 50% more.
Most bikes like your have been transmogrified long ago at a steel mill somewhere in Korea or Taiwan.
Good luck and remember the old saying about "Throwing good money after bad..."
