Looking at my first C5, it has authentic Mag Wheels.  Can someone tell me what the great advantage is over other types? 
I don't necessarily think they look knock-out gorgeous, so I assume this pricey option has to do with other benefits.
Also, any unique thing I should be looking out for when buying a pre-owned one of these beauties?
Thanks
