First day of ownership with a nice steady 200 miles, felt like 20 miles & got 28 mpg without any bother. I don't find it slow, even compared to a WRX. Mind you, I don't really drive that fast anyway!
It does drive very much like a P38, but it corners a LOT better. It's also more practical than a P38. A couple of minor stuff to sort like a lightly scuffed front bumper & interior light needs a bulb etc. But overall, very impressed & the stereo is 'stunning' even better than the Harmon Kardon from the last P38
Very throaty exhaust note too.
