im not sure what you mean about M3 look on outside there is nothing in that list that is really m3,
that list is fine though the AA exhaust and intake is good keep it
go with dde angle eyes fromj uminitza ask mike from europersona
clear corners go OEM
CF hood and trunk would look hot but i dissagree on a white bimmer looks too rice to me, if you want CF for performance purposes than get it and paint it.
glow gauges? hmmm some say rice i say they are ok, they can look pretty good sometimes.
if your spending money on suspension go with coilover H&R springs
rims? go 18's or 17's perfomance go 17's look 18's, 19's are hot but expensive and rubber is expensive to replace,
