Not many around; only 87 3.2 coupes (TOTAL) came to the US 1986-88 when the Mondial 3.2 was sold here. Best bet would be to post in the Mondial forum here (f-chat). There is also a very attractive and well- loved Mondial QV coupe in a very rare (and unique!!) color available now listed here on f-chat. temple 1988 Mondial 3.2 (black over red)
I just picked up an 86 Coupe thanks to the folks here. The dealer I purchased from was M Brandon Motorcars, but this was his personal car and he's well versed on the Mondial. There was a very nice silver one that was a no-sale on BaT, that may or may not be available. Had miles, but extensive service. Unless, your deadset on a 3.2, there are two QVs that I found that were both unique color combos and appeared to be well sorted. Feel free to PM me and I can share some more details. I do get your desire for a 3.2, though, they really do check all the boxes. I've been loving mine.
And what percentage of those 87 were red? 75%? A non-red 3.2 in the US is a rare bird indeed. Personally I'd look at all years and get the best looked-after one that you find. Good luck!
