Thanks for the comments guys.
Beauforty - I`m at the `ring with Nick and a few others next weekend so can`t make Santapod.
OliH - Its a 318d, like it says
afterall nobody would buy a 318i and put an "M" badge on the back, would they.
Squeezebm - Most of the big tuners have quads but if you want something custom made, try the powerflow website to find your nearest dealer.
