I picked one up used for my granddaughter, the day I brought it home she was about 3 or so, I know she hit everything in the yard at least twice but had a blast.
I had to put a new battery in it, but no big deal, they are not that much money.
Her older sister has the corvette version that she has out grown, the corvette is way faster than the jeep, she would get it flying down the back alley, (its paved and very little traffic), let off the gas, cut the wheel then flooring it, and spin that little car around.
Giggling and laughing like crazy. I swear that I did not teach her that.
