I was really impressed with the performance of the Xdrive and Blizzaks. My previous E90 was a 2007 335 RWD. I got stuck a couple of times with that on sideroads way back when we used to get snow(2008 and 2009)
There's no stopping Xdrive. Drove from Markham to Pearson on the 407 on a completely snow covered freeway and was really impressed.
I'm thinking to getting this mod done and helping out when we get the next dump of snow
