I'll give you GM and Vauxhall, it was the Opal Omega in Europe and yes in Oz it was the Holden but it was never released in this form. A certain little British car builders tuned it and released it as a limited run. Heres another pic of it



Another clue. It was for a long time the fastest 4 door production car in the world.

The standed version of it was only 3.0L but this was a 3.6L with twin turbos.

The reason it looks like a left hand drive is because the photos have been flipped

 

Lotus Carlton, twin turbo straight 6.

My 184MPH, 380BHP beast was rated at 170 but mine was clocked at 184 and was all as factory, no playing, no added sugar. Right up until it was stolen.

OK your up Foxxie
