The other day my wife decided it was time to look for a replacement for our Toyota Sienna minivan—look being the keyword. It’s not that we don’t like the ‘Swagger Wagon,’ or that it’s become a lemon, or even that it has been completely destroyed by our children. Its expiration date has arrived because our kids are old enough to open their own doors, buckle their own seats, and generally not make a pigsty of the back seats. (The amount of stale French fries dropped on the floor by the children might be less, but I am also convinced once free to roam the floor, they mate and reproduce.) The days of toddler fingerprint smudges on the windows and apple sauce stains—on most surfaces including the headliner, which has permanent speckled stains—have, thankfully, come to a close.
