look holden have brought out the W427( soz if misspelt) 7ltr v8 for $ 170,000 , Nissan 2009 GTR for like $ 160,000 and the GTR will not just wipe the floor with the holden but will quite possibly lap it in time around a track... and in a straight line don't even think about it . it QQ to the v8... so GTR is cheaper and a much better all round speed demon
