VW dealerships in london

[DKSA]

Hi all!
Going to be up in the uk in october (from South Africa) and by the looks of things you guys pay WAY better prices for parts than we do here!
i am after some stuff for my 9N3 5 door hatch such as the delocked boot handle, the b and c gloss black pillars. and possibly the black backing headlights etc.

I will be spending most of my time in London and then maybe off to snape, suffolk area. Which VW dealerships or parts shops do you guys recomend i go to for buying my stuff?

Thank you
Stuart
