After my leased expired for my XR6T(MKI)(SGS-165 Where are you?), I was going to get another turbo(MKII). However just before I was about to order they introduced the Monaro(VZ). I couldn't resist so I orderd that. I've had the Monaro for about 3 months now and I'm pretty happy with. Though it doesn't have the takeoff off the line like the XR6T, it is so far nice and smooth, got good low down torque. And a lot more comfortable the the T. Only problem I have is the traction control is so harsh when it kicks in, takes the power right off. The T felt like it would slow start to cut the power. As for headroom, it's ok for me I'm 5"9" plus it's not the limited edition one.
