This Coupe was posted in flickr.com by Pedro Valiente. The Coupe is listed as a Z3 M Coupe by the photographer, but based upon the Z3 side grilles and side mirrors, I believe it is a Z3 Coupe. The chrome trim ringed headlights, and chrome trimmed kidney grilles indicate that this is a 2000+ model. It is likley, however, that numerous components of the Coupe have been replaced, so they may not be a good indication.
I Googled the racing team’s name, Bas Koeten, and found the Coupe listed as a Z3 M Coupe on their site. Below are the details of the Coupe, translated by Google.
