Hi John, plenty of GTRs nocking about there, GTRs are very popular with Dutch petrol heads! Didn't see any RS6s or 4s this time but have lots on previous trips. The ISF really is the business on the track, my mate had a Holden HSV with him, which is basically a Vauvhall VXR8 , I drove both on the track and the ISF is quicker, we didn't push the cars too much, seen as we have to get them home in one piece. I know the track fairly well but was still overtaken by a good few cars, one was a corsa VXR! That guy was mixing with GT3s and R8s so he's obviously a local. The gear change and the throttle blip come into their own on the ring when pushing the car, the V8 soundtrack isn't bad either. Can't recommend it enough, maybe an ISF road trip over is calling? Any takers.
