yep on very early ones i've seen the RS flare, actually an awesome one I saw at the Ventura show some years ago IIRC a grand prix white also with orange script, a real show piece that didnt command the attention it deserved back then, they were so poo-poo'ed and now people fawn on them and sing the praise.
having bought #31 in GP white,a coupe with the blue script against popular trends in that epoch...
I knew too well that with a total production of less than 1000 made (528 coupes and 346Targas) it did not matter what the peanut gallery was echoing, it was bound to catch up and be rediscovered for what a fine example they are.
