When children make something on their own, they grow in confidence and learn skills they can use later in life to create Mount Rushmore 2. Support budding builders with today's Groupon: for $15, you get $30 worth of customized toy cars at RIDEMAKERZ. This Groupon is valid at all RIDEMAKERZ locations.

Inspired by the same brainwaves as the Build-A-Bear Workshop, RIDEMAKERZ allows visitors construct a customized toy car from the axles up with dozens of options that add up to nearly 650 million unique combinations. Guests begin by choosing a body from a stock of Vipers, Corvettes, Mustangs, trucks, and hot rods that can then be accessorized with free stock parts or specialty chassis, tires, rims, and oil slicks. The hot-lava Chevy Camaro ($32) sports a metaphor for the rubber it plans to burn with orange flames on its sides, and the jewel-blue RZ Rascal body pairs its smooth curves with working headlights and taillights ($22). Sets of multicolored or racing slick tires maintain traction while pushed across carpets, hardwood floors, or up the sides of living-room furniture ($4 for two). Glistening hubcaps ($3–$4 for two), undercarriage-glow lighting ($10), and other car accessories offer further customization, while sound-effect chips ($3) relieve vocal cords strained by persistent engine imitations. Builders can also upgrade to a radio-controlled street chassis ($25) to assert hands-free control over the vehicle's movements.
