This was mostly as the large number of Sydney privateers who usually filled the grid in the nationally televised (by Ch.7) Bathurst 1000, rarely raced outside of NSW or Queensland due to limited budgets.

[1] Despite this, young Sydney driver Steve Masterton would win the 1981 Better Brakes 3.5 Litre Series driving his Ford Capri Mk.II from the JPS BMW of Allan Grice.

In the early Group C years of the AMSCAR series, several Sydney based drivers who regularly competed in the annual four round, three race per round series became household names through the national telecast on Channel 7 (at the time, Seven's only touring car telecasts were from Amaroo, Calder Park Raceway in Melbourne, and Bathurst as the ABC was main broadcast host of the ATCC until the end of 1984).

Drivers such as Amscar series winners Steve Masterton and Terry Shiel, as well as Terry Finnigan, Garry Willmington, Brian Callaghan, Barry Jones, and the late Mike Burgmann got national TV exposure they would otherwise have struggled to get in the ATCC, or had ATCC headline drivers like Peter Brock (HDT), Dick Johnson, Allan Moffat, Allan Grice (Roadways), and Jim Richards (JPS Team BMW) been regular competitors, although Grice did win the 1982 series, Brock and Johnson contested limited rounds from 1982 to 1984, while Richards was a regular competitor from 1983 and placed 3rd in the 1984 series.

Seven's commentators for the AMSCAR series generally included Mike Raymond, Garry Wilkinson, Evan Green, and later Neil Crompton and Peter McKay, with various guest appearances by drivers not competing on a particular day.
