my bf has a 03 spec v and he is dying to get rid of it. it is slowly falling apart on him. i used to have an 01 se and it was better quality then his 03 spec. as far as speed wise, they are about the same in the end, but getting there is what is different. my MSP feels faster than his Spec b.c of how the turbo works and how it helps in acceleration. The MSP is definantly more spacious on the inside and you can actually fit people in the back, unlike any b15 platform sentra. And personally I don't like the way sentra's look, yeah I had one for over 2 years ,but I made it look as best I could with custom stuff. I can't stand the way they look stock.
