They are all up for auction in January.

At its Arizona auction on January 18 and 19, RM Sotheby's will sell a collection of cars for children that will immediately make any kid the coolest one on the block. These racers and roadsters all feature tiny engines that let actually let youngsters motor around the neighborhood at decent speed. One of them can even hit an impressive 40 miles per hour (64 kilometers per hour). 

These little vehicles feature impressive fit and finish, too. Many of them include realistic items like working headlights, turn signals, opening hoods, and even leather upholstery in some cases. 

With prices estimated at between $10,000 and $30,000, these vehicles are a bit expensive. However, they are all sold at no reserve, so there's the possibility of getting a bargain. Plus, how do you put a price in giving your kid such a cool way to speed around the neighborhood.
