I don't mind the colour - certainly stands out as you don't really see E55's in white.
However, what a crap advert. The chap is trying to sell a car that has a very limited market, and being an import it may ever be harder to sell...and he can't be bothered writing a detailed ad, listing every detail, with many pics.
If I was in the market for an E55 it would not be a white one, IMO it just looks wrong. If it were cheaper the money saved could go towards a wrap I suppose.
