The NARC championship is a SCCA/CARS championship that has a lot of history
but a pretty arcane scoring method. It has been around since 1976. You have
to enter at least two Canadian nationals and two SCCA ProRallies to
qualify, and you can score a maximum of six events of which a minimum of
two have to come from each country. It has an overall championship (for any
class) and class championships for GpN, PGT/P4, and P/P1/P2/P3. It tends to
be undersubscribed in competitors, although the list of overall winners is
pretty exclusive:

John Buffum - 9 times
Taisto Heinonen - 3 times
Paul Choiniere - 3 times
Bruno Kreibich - 2 times
Carl Merrill - 3 times
Frank Sprongl - 4 times
Karl Scheible - 1 time
Tom McGeer - 2 times

The charter/purpose of the NARC is described in the SCCA rulebook (9.4) or
the CARS rulebook (NRR XV.A).
