lol 200 R35 GTR's released every month... lets assume 100% of the buyers are ex-skyline owners (highly unrealistic, but hey). Now lets take the popular models of Skylines released in the last 10 years (lets assume anyone who owns an R32 really can't afford a new GTR, or they'd have bought an R34 by now)... that's around 4 R33's, 4 R34's, 3 V35's, 3 V36's. So that means 2 out of 14 skyline owners will be GTR owners (seeing as only R33 and R34 had GTR models). so that means of the people upgrading to the NEW GTR, only 14.28% of them will be ex-GTR owners.
now that means 28 more GTR's on the market per month because people are upgrading. Now of those 28 GTR's lets say they vary from Grade 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5 and A (accident damaged, ie ineligible). Lets also assume you'd only import a Grade 3.5 or higher car. So 4/10 of them will be eligible for import. That means we're now down to 11 more GTR's on the market that are of decent quality per month. And that's assuming ALL the new buyers for GT-R's are ex skyline owners.
Oh noes.. the market is flooded.
they point I'm trying to make is that in the last month or so, the strong change in our favour of the exchange rate has dropped the price of your average R34 GTR by about $8000. This is a significant change that is much more noticeable than the change in market value that the introduction of a car that is twice the price of an R34 GTR or 4 times the price of an R33 GTR can effect.
