Colours, bodykit, wheels, the whole scheme just doesn't work at all.
You can do some amazing stuff with cars if you're prepared to pout in some time and effort. One that caught my eye years ago was a Cav MkIII (Or Vectra A over there) that some Finnish chappies converted from 4 door saloon to 2 door coupe. Better looking than the Calibra, IMO, although I know they used the same chassis, etc.
Sadly the website that they used to document the conversion has gone, but still exists on the archive.org site, here
