To be honest some steel wheels look the business, and from a weight point of view I'm sure there's plenty of aftermarket alloys which are just as, if not more heavy than standard steelies.
Looking at various magazines at the mo it seems that a more "Retro" look is coming back into fashion, i.e. wide or deep dish steel rims with low profile stretched rubber. Some look awesome!
The end of Chavvy alloys maybe??
BBS will always look the nuts though.
