Thanks all, it will be the 320d next - 150 horse and 45 mpg with £155 tax - and a good looking motor to boot I'll be removing the swirl flaps and fitting blanking plates, from what I can work out theyre only there to cut power under traction control - not a biggie! and a vortex breather seems to solve the issue of it getting gunked up! I have seen some cracking examples for £3500 - £4000 lot of car for the money TBH
