I saw the new 328i Touring recently at my local BMW dealer since the car arrives here this month (europe)
I have to say it looks awesome and much better in real than on the pics. The car looks very muscular and sporty.... especially around the rear. The car i saw was Titaniumsilver/black with 17 inch Starspoke 44 wheels but 225/45R18 front 255/35R18 rear Radialspoke 32 wheels are available as factory order.
However this is car isnīt very big overall size and trunkspace about the same as the Audi A4 wagon.
