Skeptics be silent: Toyota's gamble to attract young customers has worked. Its new Scion line has an average age of 35 - lowest in the industry - and once you weed out parents who write the checks but never touch the cars, some estimate the real number to be 28! This sure doesn't help Honda or General Motors look too bright. Their generation-Y-targeted Element and Aztek scored big with 42 and 43-year-olds, respectively, which you might call aiming for the dartboard and hitting the bartender.The bigger surprise: the big box has outsold the little hatch. Toyota thought the normal-looking xA would be the superstar, yet droves have ignored it in favor of the xB, somewhat reducing the Scion story to one of accidental success. Maybe Toyota didn't know what they were doing after all.But who wasn't surprised? I'll admit that the thought of “"there's nothing wrong with the Toyota Echo that a Chevy Astro body couldn't fix"” never crossed my mind. That might mean I'm too much of an old-timer, but through these 24-years-worn eyes, I'll try to see what kids see in this automotive oddity Scion calls the xB.
