bet you didn't know that the skyline shares the same floorplan structure/design as the silvia....
HPI did a big feature on the linage of the GTR a while back.
I own a GTR with modded handling and it is much sharper than my Father-in-laws XR6, that said, for a big heavy car it handles well and I like to drive it.
It is not as 'involving' as the GTR, and it feels like I'm sitting on the old Massey ferguson from the driving position, but it has good squirt and makes a great family car. I'd get the XR6T especially if leasing.
