i think its a bit of an unfair test to be totally honest, the cayman has an uprated diff, expensive uprated suspension and an exhaust. if you put that on the 370z that he was testing then all he would be able to comment on is that the zed has a steering wheel that hes not too happy with the adjustment and a gear change he finds a bit sticky.
all car videos are about opinions, will has stated his so i believe its abit harsh to come back at him the way you have, hes put his opinion on here end of.
also chirs harris is a massive porsche man so he will probably be a bit biased.
