I think you will have a rather hard time hanging with 03 Cobras in the handling department. Remember, they are 4 wheel independant suspension also, and Ford seems to have worked the bugs out of the IRS this year. Too bad they haven't fixed the traction lok with something better. :rolleyes:
I think turboing the 'Tour is entirely worth it. It makes one hell of a sleeper. Just don't inflate your ego to the point where you think you can take on anything on the road.
