WHICH CAR FOR MY 3YR OLD?

[shanks]

Since tanking my little boy to watch indoor racing he wants a car!!!

So thought id ask if you guys have any ideas?

Spec required:-

1) Big is better
2) He will mainly use it indoors so needs to be slow really
3) Was thinking of a rock crawler type vehicle as i guess they go nice and slow
4) Oh yes cost - need to keep this as low as possible cause i spent to much on 1/10th electric already!! even something 2nd hand would be fine...

any ideas or anyone got soemthing they want to sell?

cheers
