you should consider a 35xdrive 2011 vs the 4.8.
the 35xdrive is better on fuel economy and actually FASTER than the 4.8 in every aspect.
id be comparing a 35d vs 35xdrive instead.
you can even get a tune for the 35xrive (i have a cobb) or also a JBD for the 35d.
not sure what your price range is but i would look into those.
2011s will be LCI so CIC and lci exterior.
you however do not get the newer headlights in a 2011.
