 2nd Review. Everything I wrote in 6/08 same except for one recurring power delivery problem. The car has small power interruptions at intermittent intervals. Very annoying but not disabling. Only set a "code" once. 3 trips to dealer to fix plus 1 with a factory engineer in attendance. Never fixed. Destroyed driving experience. Finger pointing between BMW and Dinan. Removed Dinan software but problem remained. 6SM no longer notchy. No other problems but this one caused me to Lemon Law. BMW made a deal for new 2010 w/me instead. My 535i sedan 6sm to be delivered soon. Fingers crossed. The wagon is still beautiful inside and out. It is a piece of art but this aggravation isn't worth it.
