In recent times nearest I guess is alpine A110. A more expensive car and even more niche because of the price. I believe there may be 900 or so of those sold in the uk to date. Been around much longer too.
I think there were about 1300 Ferrari 458’s sold here (coupe and spider). Maybe 8-900 F8 tributo’s.
So far I think they shifted about 800 or so 992 GT3’s, came out a similar time as the GR86.
With regard to BMW ‘drivers cars’, the old shape M2 (16-21) shifted about 6500-7000, so a lot more. However only 1000 or so were manuals……..so 5500-6000 weren’t ‘drivers cars’ at all
All in all, still pretty rare I’d say.
