I don't have alot of info, but I will say the ones my boys are asking for are the "Air Hogs Zero Gravity" and there's a zero gravity one that glows in the dark I think. I bought one for DS on
Amazon for $29.99 that doesn't glow, but I saw one in my
Walmart ad today for $25. The kids think they're cool because they drive up the walls. They got pretty good reviews on Amazon.
I know you said cars, but a word of warning, steer clear of air hogs planes, they are overpriced styrofoam JUNK. I've already gotten DS's car and it looks like other R/C cars, but it is small, about the size of two Hot Wheels put together I'd say. I hope that helps.
ETA: About the models, I noticed there were some different colors and saw one that said "air force police" on it.
