I easily remember the C3 coming on to the market in the late 60's/early 70's and even with the few you'd see in West London and perhaps in the early days ay Santa Pod in styling terms they were years ahead of anything else similar, except perhaps the Lotus Elan Plus 2
And the highly exotic (and expensive) Maserati Mistral
and the visually very similar Frua styled AC428
