To be fair, the conditions suited the GT-R far more than the GT2.  And as MKSGR pointed out earlier, the GT-R will not be putting in these sort of laps consistently due to wear on brakes etc (weight driven) whereas the GT2 could consistently do this sort of laps for a lot longer.  Bottom line is, the GT-R is a very quick car even if you ignore the price.  But will I use it as a regular track car?  Not unless you are willing to spend the money replacing gearboxes, etc.  Btw, one of the privately imported GT-R in Australia (officially Nissan sale starts next April) has blown an engine.  Replacement cost?  $90k!  So if I buy this car, I think I will keep it away from the track and make sure that I sell the car in 3 years (once the warranty runs out)...
