lol speak for yourself Zebra!! I wave at almost every E90 i see and less than half the time do i get anything back.
i find with the sedans, there's a lot more "normal" drivers who don't really have any kind of enthusiast mind-set, nor do they notice others on the road. your average middle-aged woman driving a 323 is probably not going to wave back LOL.
