This is an ultra rare Belgian built Tr 2 Francorchamps coupé. The cars were built in the old Imperia factory at Nessonvaulx in Belgium. Only 22 Francorchamps coupés were ever built, of which only 3 are believed to have been the long door version, as our car here.

The Francorchamps was a more luxuary version of the normal TR, with different door and rolling up windows instead of the plastic side screens. The fixed coupé had a special plexi sunroof that could be tilted open. The predecessor of a targa and panoramic roof.
