If it is that new and in prime condition- It could be ripe for an upgrade to more gears- 8, 9 or even 10 speed. This would also involve new wheels and Changers(Brifters possibly) but with your expertise on "E" Bay- could be a very cheap way to a "modern" bike. But if the bike works well after your "Test" ride- You still have a very nice bike.
