He probably thought you were crazy because none of them have 180km/h dashes. It's a Jap spec one and the speedo goes to 340km/h.
He was lying but that's life, the Nissan guys who are touring with this car are getting pissed off at everyone asking the same question but to everyone's defense they needs to stop lying and come out with some genuine details.
The silver is a nice colour at night but I like the other colours more. The silver also costs $3k more as an option. Probably $5k by the time we get it here.
