A very early gr.a m3, and some famous faces behind it. I recognize a young Marc Hessel, Van De Poele next to him, Altfred Heger, & Emanuelle Pirro.
You can tell this is a very early car by the mirrors, these are borrowed from the previous gr.a project w/ the e24 6 series, also the fog-lights still being in place, I’d say this photo was taken in 1987. I believe this is also the same car used in the BMW promo photos with it and the std. road car in red.
