I never imagined my kids would have any toys in common with the ones I loved at their age, but both of them go mad for Hot Wheels cars... just like my brother and I did in the late sixties/early seventies.
I remember we had a red custom with a bubble roof like Ed Roth's 'Mysterion'... I think it may still be in a box in my parents' attic. And my son has his favourites too... he definitely favours the hot rods over the muscle cars.
That's my boy.
