So, after 4+ years in my tuned/lowered B8 S4, I decided it was time to move on. Sold it to a local(-ish) German car enthusiast and replaced it with this:
CPO 2013 S6, Glacier White over Black, all options except B&O. What an amazing car!
SO fast, SO comfortable, SUCH COOL tech (even if only 3G hotspot capability).
Really enjoying it, even if it did start steering itself the other day (stoopid lane-keeping-assist button, be less hidden!)
I'm grinning like an idiot anytime I'm driving it.
