Not meaning to be rude or anything but the S5 isnīt really all that much of a WOW-Car.
Sure it looks nice (especially in white) but thatīs about it & to compare it with an AM even at a glimps? I dunno but I did get the chance to check one out while I was looking for my new fun-mobile and the car over all is just too much in an all round comparison than the M3 is and sure itīs cheaper but it also has much less fun in stock, so Iīm glad I got my M3 DKG and havenīt regretted it one bit
