Well here's a copy of the email that I've just sent him. Short and sweet!!

Hi, thanks for your response.
I absolutely love your grille, it would definately stand out here in the UK! Unfortunately, I now can't make my purchase, solely because of this communication with a fellow XF owner:
"I honestly dont care what you want. Hows that sound?"
Regards, Andy.

I really hope they realise that they can't talk to potential customers like that!

Regards, Andy.
