6. There was 3408 produced (351 known manual coupes) and the ENR34 was available as the 25GT FOUR (sedan/coupe auto and manual), 25GT-X FOUR (sedan auto) and 25GT FOUR L Selection (sedan, auto or manual)
You can see the differences in specs between these varieties here:
Series 1 4 Door, 2 Door Series 2 (although there are no manual coupes)
That's all I got.
