I am new to this community. I bought a "New" 2006 Xterra S 4x4 MT about 2 months ago. I love it, haven't managed to get it stuck in stock form as of yet. Actually at about 1100 miles I was wheeling it with temp tags, lol. I came from an Altima, so I did take a little plunge on gas milage. I still manage between 20-21 MPG though. Hope to learn some good stuff from this community. Take care.
