E38 750 "sport" body

[Blues]

I have the standard car, which drives like a dream, but would quite like to update its looks.
I also have an E39 540 sport - and that is the look i want to achieve. Has anyone had this done, if so where and what sort of price should i expect to pay.

I must stress, that i want the slightly understated, sleek look - definately not bling or "Barried-up".

Thanks for you help chaps
