Yeah, I have bought those, 120 small rc race cars. They are pretty nice, they aren't your top of the range but for the price fairly decent. Typically they sell for $18 plus around $5,45 shipping now whether they sell for that price I don't know however, I bought a shipload of them, including shipping for approximately $520 and they seem to be selling fairly well.
Personally I sell mine here where I live for $10 and have sold a few already and on ebay and amazon way under cutting the $18 mark for $14.99 including FREE shipping and doing fairly well. Personally as a newbie myself to all this I think they are a great beginner choice, those and the large trucks you see on sale tend to sell really well.
If you buy them put up flyers in your local stores and walmart they tend to sell fairly well, as for the condition of the cars and value they aren't top of the range but for wholesale at $5 to you and sell them on for EVEN $10 you will double your money!
