Thanks for the replies.
I'd say "20-25 more hp than an M3" equates to "near M3 performance".
I am just toying with the age-old question of Should I SC my car or lose 2 doors and go for the M3?.
As SC are becomming more popular I am thinking the answer to this question is changing. I am still a year or so from deciding. I will continue to look for SC updates.
Thanks again. Please keep the updates coming.
