My ongoing midlife crisis vehicle swerves in a different direction: I bought a 1988 Nishiki 1207 at a yard sale for $40. Mostly stock save for a new seat. With the wheels out of true, the stickers plastered over with garbage, the brakes loose, the front tire visibly cracking, the rear cassette visibly rusted, and the rack mounts stripped, the bike needs some work. I am motivated to finally really learn bike maintenance after putting it off for 30 years
It's a rewarding project! I fixed up a freebie old Schwinn roadbike a few years ago and it's so much fun to ride. I have a freebie Nishiki too waiting for a decision on what to do with it--touring bike or fixie conversion. Enjoy the time turning wrenches and then on the road!
Riding on a wheel you have built from parts is a joyous thing.
