I have two vintage bikes I restored
The cumulative to do both bikes right and acquire the vintage componentry I wanted easily cost 2/3rds what I just paid bikesdirect for a new Moto CF Imortal Force.
I learned a valuable lesson.
Restoration of vintage bikes is an expensive endeavor.
(I won't even go into the shill game and last minute outrageous bids encountered on eBay)
IMHO..Unless the (vintage) bikes componentry is reuseable or the bike has deep sentimental value you're better looking at a 9pts out of 10 version on craigslist.
