Guys, although I am still looking for '07 Xterras, since they are few and far between I am starting to explore the option of low milage '06s. Is there any differences between an '06 and an '07? Do the Off Roads still have the Skid plates and locker rears and "the triple-cone synchos in second gear" (whatever that means)? I am assuming the same engine means that the HP and MPG are the same. Is that correct? Thanks.
