Well, it wasn't "vintage" when I bought it in 1985 ('84 GT). Arguably, it's aged more gracefully than I have.
(still own and ride it)
Found this 2000 Fuji Newest with a "FREE" sign on it. It was in pretty rough shape. Cleaned up well and needed a few parts. Much lighter, can ride faster (yes, even with the reflectors), 9 more gears but by no means a "modern bike"
