Just saw a preview of the car on the replay of today's BJ coverage on Velocity network.. it was parked in front of a yellow GSX.
Nice looking car. They called it 'pearl white' paint, and the interior has some custom touches like cloth seat covers and a white-rimmed steering wheel.
Funny how they mentioned GM limited engine displacement to 401 cubic inches for the intermediates (error!)......actually the limit was 400 which is why Buick called the 65-66 GS 401 a '400'.
Looks like someone got a good buy, if you like the customization.
Edit: The GSX was a '72 Skylark, 4 speed, sold for $16,500.
