my son loves this car, he loves hes got a door to open and close and he can pretend to put petrol in his petrol cap,he has a radio that makes a siren noise the wires not very long on it but i guess its for safty, i thought it was a bit hard to build, i had trouble with roof and the 2 front parts to keep them on, they kept falling of every time i lifted the foof to put it on the car but other than that it was quite easy once you got going, its all worth it in the end once you see your kids face light up with joy,
