On the demo side I knew one who was 57 (year ago, so now he is 58 i guess
). But not as old as Doorman.
I don't care how old someone is, but generally there are no wreckers among senior racers (well never met anobody so old that his/her reflexes are already so slow that he wrecks because of that). But the idea of a 60+ year old wrecker granny is just plain absurd
