Actually, this is wrong too. If you were to go by that old first-cut sheet, EVERYTHING 16V is supposed to get classed at 30%. In EVERY class. Just simply didn't happen like that. In every class 25% was used. When the first 16V car that was to be classed for ITB hit (MR2), all of the sudden 30% was 'what we used'.

I don't care who you are or what your recollection, this is what happened. I can go back and look at every ITA car that was classed or reclassed and prove 25% was used. I ask those who fought for 30% on the MR2, where was that 'fight' when every other car 16V was being classed?

Ugh.
