The trouble is your going to get the anti japanese car people not matter what facts you have . other factors are that the gt-r has a 3.3 and could be quicker on edmunds video. another factor is the gt-r which is out now isnt the top of the range performance on as the v spec version is due out which is lighter and has more power.so any results atm are against its base model only. all the cars mentioned are great but once again price performance and handling have been a break through for nissan and carrying on its cred,
