They didn't just stick to the engine and apart from suspension mods, sports seats, BBS alloys and the Motorsport Steering wheel were popular mods. These Motorsport versions could be identified by their motorsport stripes and by the widened power bulge to accomodate the carbs (see below, I tried to make it easy to compare the Motorsport hood with the stock version right next to it).
At the 2015 Sharknose Meeting in Holland we saw a wonderful example of these rare cars, fully original and with the entire package installed! Pics below.
Thanks to Raymond for pointing me in the direction of this special vehicle otherwise I might have overlooked it at what was a busy day for us!








Feel free to comment if you have additional info or if I'm incorrect on some sections. Anyone know production numbers?
