Mate, I've got one of these sitting at my parents place. Its a four door, was factory black with red interior (pimpy!!) Came with a 390 FE Motor and C6 Trans. Have never had much luck searching for info on it. They were Australian Delivered, have had a fairly average RHD conversion done ( brake booster/master cylinder is still on left hand side of car with a dodgy bar actuating it from the brake pedal). Also has a fibregalss scuttle grill (below windscreen) which may have been due to conversion as well. I would also like to know a bit more about their history especially how many were imported.
Here's a picture of a two door one
And a wagon
