Help needed please! I'm on the verge of ordering my new golf (r line estate) but have been unable to find "samples" of the colours I'm interested in. Unfortunately my local dealer has no cars of the right colours in stock,nor do they have any colour samples. The colours Im interested in are dolphin grey and the oyster silver if anyone can help? I've tried using the vehicle configuration tool on the website but it doesn't give particularly good results!
