The first Amaroo meeting got canned because under the V8 touring car rules the cars had to run a CAMS supplied electronic box (I think it was a rev limiter) and CAMS would not supply them. It all happened at the last minute. Plus there was a problem about the control tyres. CAMS didn't want to allow the cars to run on control tyres and insisted that the cars follow the existing V8 rules. (but when Avesco wanted to do it they bent over!)
So the meeting went on as a very expensive sponsors joyride day.
The first Amaroo meeting also clashed with the V8Supercars round at Symmons Plains, which also got AVESCO going... The first Super Touring round of that year also clashed on this day, at Lakeside.....
From memory, the series was originally going to be called the ARDC V8 Challenge or something, but AVESCO and CAMS objected to the word 'V8' being used, so ultimatly the series was called the "AMSCAR Sedan Series". Goodyear as mentioned was the control tyre supplier (i recall some arguing over the wheel sizes with CAMS?)
The calendar was originally;
Rd1 - Amaroo
Rd2 - Eastern Creek
Rd3 - Amaroo
Rd4 - Eastern Creek
Rd5 - Bathurst (as a support race for the AMP Bathurst 1000 for Super Tourers)
N/C - Eastern Creek
As mentioned the first Amaroo meeting was canned by the powers that be, the Bathurst round was axed because of not enough entries (did AVESCO threaten to not accept their 'rebel 1000' entries?), so the orignally non-championship Eastern Creek round became the final round.
Mal Rose won the championship in a Commodore. The races were covered by Channel 7 (though late-night highlights). Other competitors included Allan McCarthy (i think he won the first round or two), Mike Conway, Gavin Monaghan (in Conway's old VP).... i think Bill O'Brien even ran the Everlast VR maybe
