Ok so im an ex-owner of the na xf,and upgraded to the srt.what really gets me is how anyone could even compare the two.of course the na looks great,is stylish,a great car and is a great value.but for some to say the na is even in the same league performance wise on a mountain course or otherwise is absolutely absurd.ive driven both hard in straight lines and through very curvy roads.the extra hp combined with the beefed up suspension which creates less body roll would make short work of the na xf.i would gladly prove it to anyone that has the na and is up for the challange.now i will not stand here and say the na guys or gals as a whole have an inferiority complex about their na,but its very clear that some do.
