As ungainly and corporate-GM as they are, the Colonnade cars easy to distinguish in any form, with uncommonly resplendent proportions and an unmistakable greenhouse. In Grand LeMans form, this particular Pontiac coupe is a nice representation of the body in a more standard configuration, justifying its well-preserved state despite a less-than-sizzling reputation as a collector’s item.
Its rear end styling was also better at emphasizing the curvaceousness of the basic shape, compared to the more popular A-body variants, making this slow-seller when new one of the more rare versions of surviving Colonnades today (though maybe this isn’t the case in Canada, where AGuyInVancouver shot this).
Big coupes were where it was at in those days and it was hard to top GM’s intermediates when it came to gravitas; that’s easy to forget for those of us raised in the post-Taurus/Accord era. As generic American cars of the seventies, there were more boring shapes out there.
When it came to the standard A-body, the Cutlass Supreme was vastly more popular, suggesting this nominally-deluxe Grand LeMans (nee Luxury LeMans) was somehow lacking. I can’t imagine why, given how much this car shared with the more popular–and expensive–extended wheelbase A-special Grand Prix. If space efficiency didn’t matter, and if personal luxury was the watchword, this interior should’ve been what most consumers wanted. I’ll leave it to you guys to explain the LeMans’s relative lack of success.
