Can I modify a Porsche Boxster? I currently drive a 2011 Subaru STI. I'm looking for another little sports car CONVERTIBLE. There's no Porsche dealership in my town and it's and hour and 1/2 drive to the nearest one. I heard the Boxster is slow, on paper it's slow then my STI. I have no experience with mid engine/rear engine vehicles. Would it be easy to add more power and actually make it a fast car? If so what?
