Query: One word of warning...

I got this for my 3yo son for the holidays. He asked for it specifically. My one word of advise would be to remove the batteries so that the toy is silent. Otherwise it makes the MOST annoying 'revving' sounds constantly. It drove me completely nuts just having it in the cart at the store. It's perfect once it has been silenced!
