My man maths took me to the S4 and Michaels awesome colour scheme one :-) Same when I bought my Maser started off with 4.7 auto and ended up with MC shift :-) and that took me 6 months to find one I wanted, same with my 996
The S2 being wider sounds better as I'm 6ft2 and having tried Caterham style kit cars it felt like I couldn't move and driving experience not as fun could barely keep my feet on the pedals.
I'm happy to wait until the one pops up, so love side pipes which I bet will be rare as hen's teeth in any of them, assume was an option. I've seen the post that lists out the numbers made for each series and S2 seems to be very limited, adding a roof is like winning the lotto which is more fun as makes it rarer and great fun to get out on the road.
