How precise do you need to be, I noticed on the facebook page there are pictures of Skyline GTRs in addition to a GTR.
By the way, Porsche were at Winton Saturday, they seem to have 911 GT3s, 911 Turbos, 911s, Caymans, Boxsters, heck there was even a Merc sitting happily in their club.
I must admit I'm one of the ones who dilute club Nissan Skyline, I have a Nissan Silvia.
I originally joined Nissan Datsun but found them to be mainly in to rallies and their track day was disorganised. A mate from WRX club mentioned they ran with SAUVic who seem to be well run and friendly. I was a bit unsure how I'd be treated by a skylines group, I was pleasantly surprised to find out how welcoming everyone was and how much people knew about other Nissans like mine, suppose we're all a collection of parts from FAST. Long may this continue.
