When my son was little he had a John Deere ride on tractor which back then (he is now 10) was about $500 and they are now circa $800 new. DD who is 3.5 loves Barbie and I saw the battery operated barbie cars. I noticed they come in 6v and 12v but would imagine the 12v to be faster/better. I'm a bit concerned however as they are so cheap. Does anyone have one and is it as good as the John Deere tractor's or are they cheap piles of junk?!
