This isn't nearly as cool or rare as a lot of other bikes in this thread, and I'm not even sure I'd call it grey, but here's my entry.
This is is my wife's Specialized Sequoia Elite. I bought it from a widow who said her late husband had ridden it from Boulder Colorado to their home in Peoria, IL prior to his death. Wifey is a casual trail rider, so I guess this old girl saw her glory days a decade or two ago.
