Judging by the 1st photo (shown below) it appears to be Mandarin Orange (metallic) & Buckskin (metallic). In the rest of the photos it almost looks like Firethorn Red. Unfortunately I don't have the interior availability chart to see which accent colours were offered with white interior. What Chevy offered was white with either black, blue, medium green or Firethorn carpeting & dash. 

You know, I have had my '77 Le Mans brochure since September 1976 and was aware of the GT option, yet I have only ever seen ONE in person. That one was silver & charcoal, seen on Jarvis Street in Toronto back in the 1980s. I have also seen pictures of a dark brown & tan one, plus one in white with dark blue.

It is funny but in my Canadian brochure it states "two of Pontiac's toughest V8s are available". In the U.S. they offered a 301 Pontiac, a 350 Pontiac (or Oldsmobile in California or high altitude); meanwhile in Canada they offered only Chevrolet V8s, a 305 or 350. Even the sixes were different, with Buick 231 V6 (U.S.) vs. Chevrolet 250 L6. (Canada).

I think I posted this before but worth another look. Interesting colour combo. 

Todd, mine is the Canadian version. Actually there is a Canadian version online here: http://oldcarbrochures.org/index.php/Canada/GM-Canada/Pontiac/1977-Pontiac-LeMans-Brochure

You could get just the over the roof stripe, or you could go for the GT package that included the 2-tone paint, striping, Rally II wheels, RTS (Radial Tuned Suspension with stabilizer bars), Grand Prix instrument cluster with gauges, and dual sport mirrors. They also claim that a blacked-out grille was included but I believe that is incorrect on a '77.

The Sport Coupe model itself came with the louvered side windows and according the the brochure, RTS. Gauges were an extra cost option. I can't remember if the Sport Coupe also came with the additional tail light segments on the trunk but I think they did. The Can Am is another story...

Too bad the GM Heritage site doesn't have the AMA specs online for Pontiacs the way they do for Chevrolets.
