Thanks to all for adding,
What I remember about my sister's cars, is that the 'Front Valance' was fiberglass,
and it had a small wind-dam built into the lower section which looked pretty cool.
The Formula SD-455 car was very clean looking, and did not have all of the 'Billboard Graphics'
like the 'gaudy' Trans Am.
And the Black Interior, with the Rally Gage Dashboard, Bucket Seats and Center Console was a
General Motors 'gem package'.
The young guy who had owned it, was the original owner, and his father was the Sales Manager at
Lockwood Motors {Pontiac} in Peekskill, New York.
Since we were a Mopar Family, my sister became 'turn-coat' when she told my Father she wanted
that 1973 'red' Firebird instead of a 1973 Dart Sport 340.
But to be honest, we did not know how rare that 'Formula' SD-455 was, or how quick it was.
At the time, I had a 1969 'M-Code' 440 'Cuda with 3.91 Gears, which was one the quickest
'Street-Stock Cars' cars around.
But my younger sister could stay within a 'car-and-a-half' of me with the Formula SD-455 with
the 3.73 Gears in a straight-line race.
For general all-around driving, and racing on winding roads,,,,,,,,,,, she'd destroy me.
That red Firebird could fly...............
