Having thought about this a bit more there isn't a colour I
don't like for the VW Transporter. I'm equally attracted to 'utility' factory stock vans in non-metallics & blacked-out blinged-up pearlescent Sportlines on 20" Range Rover alloys. I'd not considered beige before but some of the Classified ads & those in VW brochures look very classy with big silver wheels on.
Whilst understanding whilst some people want to avoid white for a Cali I think the current white-with-black trend for German cars (Mercs, Audis, Porsche, Golf GTIs etc) looks brilliant - I'd have a white VW Up or a Polo GTI as well as if I had anywhere to keep it.
Having said all that I ended up with Acapulco Blue which brings a (teeny) bit of Cote d'Azur to a wet weekend in Yorkshire
