After 7 months of watching the classifieds, I finally found a 335i xDrive with the color combination and options I wanted! Unfortunately, it's halfway across the United States! Tomorrow I start a road trip to trade in my car and bring the new car home. Until then, my 328 is back to stock and all washed.
Once I'm back home, I'll have a 2014 328i M Performance Exhaust for sale as it won't fit on the new car. Feel free to PM me with any offers. I paid $900 new. It has a few thousand miles on it, perfect condition, and sounds awesome. You will need a new clamping bush (coupler), but I have the part number and it's $50.
