Yeah, that was the test mule.
It had an Anni interior, and recaro seats, flared wheel arches (about an inch wider), longer front bumper (final production car's is squarer and flatter)
Can't remember who made the exhaust pipe on it (it certainly wasn't sebring, like production R32's were)
It had SuperTurismo OZ wheels
This particular R32 was the one they pounded around the Nurburgring to fine tune the chassis set up, so it's basically one of the Daddies!
