I think the Xfire is as cool as a Z, top points for styling and design ect but I dont think its faster, in every magazine test it was'nt and the specs also prove that. I keep reading about people going crazy for mod chips and I just wonder why... but its down to personal preference. I agree the rest of the Nissan lineup is ugly/shiny plastic looking but I think the Z was very well designed, by real designers (if you research you'd know) I dont think the same people who did Maxima's where from the Z studio. (is'nt it obvious by lookin?!)
