What do you say when non-cyclists ask you ....

[run it, ride it]

"Notice how I carry it through two tricky doors, into the basement, and then double-lock it to the welded steel railing when there's a bike rack right outside--as opposed to leaving the keys to my van wherever I happen to toss them when I drive that in to work? I'll let you draw your own conclusions."

I tell 'em outright $400, and then tell 'em all the cool things I've done on it, and how it's probably saved me that much in gas already. They'll usually follow with how much they want a bike, but can't afford something expensive like mine (!) and I give them name of my LBS, which specializes in good used bikes for less than my new one cost.
