I own a gtst also but its not simply a difference of $15k but common sense that tells u the price 4 GTR's has dropped dramatically, allowing u to purchase much more for a lower price.
I tink we'v all spent x dollars too much. but imagine wot we wuld hav if we only had waited one more year, instead of spending ontop of a RB25... hey GTST Vspec
Jus a premise..
