I grew up...not far from there.....and delivered the morning newspapers in that area (late 60's)....
There was about 5 or 6 major new car dealers...close by........and Bow Mac was the oldest Pontiac dealer in Vancouver.....
It was quite the site....for new model intro....with all the fancy signage...and floodlights
My 64 Parisienne 'vert...was sold there new......and traded in...a year and a half later......I bought it from the second owner......on 03......(still had the protecto-plate...in the owners manual)
