That is not a P-111, which superficially looked like a P-300 but had an emission motor with single coil distributor, and recessed side marker lights and a different rear bumper.
This is a Bob Grossman special, which were both P-111 and P-300 cars which were supposed to be fitted with the 3 liter motor courtesy of Lenny’s in Toronto…the EPA caught wind of this and Bob paid a big fine and the cars remained as is.
The only one which made it through to the US [long before the grey market] was a gold car in Michigan # 20152.
