Yes and No or should I say No and Yes.
No it will not make it any easier to import the previous models into the States.
Yes, if they make it into that bastard child of a model then I (along with other's I guess) will pay the high price to have an R34 imported in and converted over.
At best it may get MotoRex to bring their prices down some or maybe others will also start importing the older Skylines.
