Little Tikes Cozy Coup outsells any other car.

 
457,000 of these little suckers were sold in 2008. That’s a whole lot of molded plastic being churned out at a rate of one car per minute. At least it gets good mileage. Earlier this month, the toy car was inducted into  the Crawford Auto-Aviation Museum in Cleveland.
