I can never get my head around this "never buy reps" malarkey, there are probably some makes of replica wheels that are just as good if not better than some genuine "branded" makes (I'm not comparing like for like here such as genuine BBS V's BBS reps obviously), just do your homework and buy form a trusted or recommended source.
Does make sense though in this case to go for the genuine ones for the sake of a couple of hundred quid.
