its been a little more then a year since they started selling the E84 around here. and i see about one a day. compered to me seeing at least 100 3 sedans a day and about 40 of the 5 series, ill see about 40 X5's,20 X3's..ect.. but only one a day if not any... still have not see one rolling around here looking better than mine
but i also have an E88 and i only see one maybe in a month... and the rarest sighting would be the Z4, maybe one in a three months
