Hot Wheels RC iNitro
"The radio-controlled Hot Wheels racers won't hit 100MPH, but it also won't decimate your bank account. The itty-bitty Mustang GT we tried out is, after all, just a toy -- and not the kind that bored rich men buy themselves. It's plastic, relatively cheap ($33) and designed to work with every kid's favorite touchscreen device, the iPhone."
