If i could afford to drop 50k on a car, maybe try import a NSX-R but doubt thats doable for 50k.
TVR Sagaris probably or a Ferrari 355, or a Nissan GTR if i was feeling more sensible, the only turbo i would have.
Apart from the GTR none of those you can use every day, that is the secret to a Porsche, there is nothing else that goes that well and does everything else so well that you can drive every day.
