I was leaning away from the 660z till I read your replies, thanks all.
Also watched a vid on YouTube from some Aussie!!! Dealers in the morning 👍👍

the R has a 0~60 of around 5 sec so provided you can keep the front down, you can dance with smaller super sport cars.
In fact you can extend this to 80mph if your change gear is spot on and avoid the brick like limiter. Beyond this aerodynamics and not enough horses start to slow you down
