 Wonderful car with a strong luxury feel. I've owned the car about a year and driven it about 7,000 miles.  I did have to replace the thermostat since I kept getting a service engine light.  Another problem is missing pixels in my instrument display and radio display.  This required replacing the instrument cluster and the MID display.  Electronic parts are very expensive ($1600).  Since the car was out of warranty, I wrote to BMW to see if they would assist with the repairs and they said they would.  Put me in the BMW good will program and agreed to pay for the parts if I paid the labor.  Good deal for me, nearly $2000 worth of repairs for less than $175.
