If I am looking to buy a sports coupe and do not need 4 sports seats, then definitely 991 C2S for me. At least it looks like a sports car unlike a M3 coupe which can be mistaken by the less discerning as a regular 3 series coupe. But if you want a sleeper look, then you will skip the Porsche.
But the 991 is at least $100k more than a V8 M3. So it begs the question is it worth the money? And then you will ask why not spend less for a Cayman S with PDK and sports exhaust? The Cayman S in stock form may look a bit odd from side view but slap on Techart kit and it is a looker.
In terms of interior, the new 991 is gorgeous. At least it looks expensive and the centre console is fully utilised unlike say the M3 where there is plenty of unused areas. I would have loved to have crowded buttons even if I don't use them.
I have yet to test drive one but the general feedback is that its steering feel not as good as the 997. But the pluses from the rest of the car will still attract buyers.
I only have a Boxster S but it already feels more nimble then the M. I like the M for the engine note and M exhaust combo. It reminds me I am driving a V8. But my Boxster S also comes with sports exhaust from the GT3. It is a different sound but it just opens up at higher rpm to sound heaven. Very different from M3 M exhaust which is not loud at higher RPM.
PM me your number. I am moving to near your place in Sep. We can kopi and talk cars hehe.
