Hello, everyone. Its been a while since I've posted on here since I got rid of my 04 330xi, but after having some non BMW cars I've decided its time to go back. Specifically, to the M3. I've been looking at the market and am having trouble deciding between the 2009-2011 model years. I've done some research online and wasn't really able to find a reliable list of differences. I know that 09 is when they added the updated iDrive, but other than that the only thing I've seen is updated LED tailights in 2011, but I'm not sure how true that is. I've also heard they changed the type of leather or colors of leather in 2011 but again not too sure? Would any of you know some of the differences? Also, any tips and recommended packages/add-ons you'd recommend getting on the car would be appreciated. I live in Indiana and the weather here can get pretty bad in the winters so I was going to just throw some snow tires on it to get around as it will be my daily driver. Thank you again!
