So we've established the SC has more power, how about the other options that are part of the SC package? For conversations sake, the 2k price tag increase of an SC covers the actual Supercharger, 17" rims, real sweet seats, titanium colored interior, etc. Now if you were to supercharge the xterra, it would cost 2k alone just for an aftermarket install. Premium fuel or not, the other added options out-weigh the cons for me.
