Unless you've raised your tween off the grid, he or she is probably a card-carrying member of Gen BuY -- Generation Y kiddos who can spot a name brand from 200 paces. So why should the car you drive be any different?
Motoring into the school's carpool line-up to collect your tween in a road-worn minivan or paint-peeled pickup is probably cause for alarm. You may just have to wait until your tween comes out of hiding before leaving for home.
It's not merely a matter of economics, though. Even if you drove a luxury brand, you would surely do something mortifying -- like roll down the window or listen to public radio.
