Q greeting?

["Ian J Haseltine" <Jim_Haseltine@classic.msn.com>]

I came very close to ending the life of a cyclist tonight, the guy is damn 
lucky to be alive, 'cos he could give the SAS lessons in camouflage. He was 
dressed in black, no lights on his bike, on an unlit country road in the 
pouring rain - I only saw him at the last moment . Venting, I shouted some 
advice to the effect that it would probably be a good idea if he bought some 
lights as soon as the opportunity presented itself. 
I assume that he is in fact a fellow quattro driver as his reply of "4Q" is 
obviously an Audi greeting with which I am unfamiliar.

Could it be that a greeting of "4Q" should receive a reply of "4Q too"?
