This thread is kinda of peculiar to me. I am just wondering how many ppl who purchased a M3 thought the drive/feel was so bad to want to immediately sell it?
As all of the forums, online/YouTube reviews, and sales numbers indicate this is an incredible car. Best car I have ever owned (as most M3 owners attest to). There are so many other features about this car that seems to me trumps any qualms with the feel/drive. Lastly as many posters have mentioned, there are ways to address that short of selling it (change tires, change tire pressure, change from standard to Sport mode, change to chill mode, etc).
Ok, just had throw my 2 cents in here. To the OP, good luck with the sale and hopes it all works out!
