Major model year changes in W221




If you have a car that you don't like, sell it and get one that you do like. I have five Mercedes and a Maserati, and love them all. The Benzos that I own today (GL450, S550, SL550, SL600, SLK230) are the 20th thru 24th Mercedes I've owned. I think the W220 was the least reliable; it never stranded me but did need some repairs along the way, more than I thought it should have.
Other things I am interested in are:
lane keep assist
pedestrian recognition on the night vision system
electric power steering
blind spot monitoring
Did these things all come in on the 2010 model or were they phased in on different years?
