I've been fighting the urge to buy a GT-R for a few years. It just didn't make sense to have both the GT500 and a GT-R and I wasn't ready to part with the GT500. I was checking out the GT-R forum and noticed several threads on 2015 pricing. $20k off on 2015s seems to be the norm now. At that price a used 2012+ doesn't make much sense. So, I've been shopping 2015s the past couple of weeks. I'd keep the GT500 for the time being.
