Okay so there’s no way to know for sure, but the writing style is unmistakable.

1976 WAS THE LAST YEAR OF TRUE MUSCLE CARS TO MOST PEOPLE

Who would claim that? And to so shamelessly claim that in all caps...wow.

The whole text has a...strained relationship with the truth.

SOLID MYBE ORGINAL PAINT—STRAIGHT AS IT COULD BE—1976 WAS THE LAST YEAR OF TRUE MUSCLE CARS TO MOST PEOPLE—BOUGHT THE CAR NEVER EVEN TRIED TO FIRE IT UP YET,DON,T REALLY WANT TOO SELL IT BUT MOVING OUT OF STATE—SO IF I SELL IT OK OR NOT IS FINE TOO.

As the owner of a mechanically identical 1976 Pontiac Sunbird (hello LeMons!) i can tell you...there is NOTHING muscle about the buick 3.8L in these cars. 105hp. 4K redline. Yeah. Also, i’m guessing he’s actually got a 5-speed in there but just doesn’t realize it since its a dogleg, with first down and to the left.
