RItchey Road Logic, purchased new in 1997, with 8sp Dura Ace, at a steep discount because 9sp DA had just come out! I kept it 8sp till last Fall, when I realized I was not riding it enough, so I swapped the 7400 series STIs and rear derailleur for 7800 series to give me 10 speeds and the ability to run a 12-30 cassette. I kept the 7410 crankset, because it's The Most Beautiful Crankset Ever Produced.
I don't think of it as 'vintage', oddly enough, even though it's at least 26 years old.
