I have a 2010 Sport and recently I have found myself looking at the new 2012 GTR and the new C6 Grand Sport. Also a few P-Cars. I have owned several C6s and a Z06 the Nissan is a beast but afterall it is still a Nissan, Had a 09 Carrera the wife hated it I was not too fond of it myself. Now I am thinking about the new 6 coming out with 400HP and gobs of torque. So I am leaning towards the new 6 or maybe a current M6? It is ashamed the current 6 doesn't have many choices to upgrade HP Without spending several thousands So you would be better off getting an M6.So my ? is should I try the new 6 series or get the current M6. Decisions.
