A rental car is the fastest car.
Rougher ride than I expected but it is hard to keep your foot out of it. Not sure if these pipe sounds in or the turbo is right in front of the firewall but you can definitely hear it in the cabin. My Legacy GT might as well be an electric car in comparison. I'll post up some driving footage if it's any good.
Thanks again to Skychismo for the driving route! Had a blast.
