Ha Ha... i envy you US guys for your great aftermarket parts and wonderful landscapes in the states. But when it comes to speeding you're far away from "land of the free" as every country except good old Krautland ... Last year i was at 295 km/h (roundabout 180 Miles) and it was pure curiosity how that feels. Until then i was only co-pilot when a friend of mine goes 330 km/h with a Porsche 911 Turbo tuned by Ruf...completely crazy, my hands felt sweaty.
Driving that fast is really demanding and a bit scary ...Sometimes it's nice to push the throttle but honestly i prefer a top speed of roundabout 120-130 Miles as there are too many idi... äh guys out there that haven't grasped yet what the purpose of a rear view mirror is...
Finally i enjoy the car much more on roads with nice turns where top speed is a relative figure. So don't be too sad with your speeding limits...
