i am not sure how you can compare a 4 seater coupe to a 2 seater convertible, unless you doing a trump car style comparison with hp, 0-100km/h stats etc.
suppose it all comes down to what you after, talks to the soul and puts a grin on your face.
If it was my every day drive id take the M2.
If it was my weekend drive where id take the car to a pass outside the city, and enjoy the precision and balance of the car then id take the Porsche.
Don't get me wrong, not saying the M2 wont have that, but i just see the Porsche as more of a polished,refined, precise driving tool.
Either or, cant wait to see either in action
