 2009 BMW 535i idrive w/sport pkg. By April 2017, had only 60,000 driven. Very disappointed with this ultimate driving machine. For me it was an "ultimate nightmare machine." Started with--heating system, passenger freezing, driver boiling up (heater master control on driver side). After warranty expired in 2013 to 2017, almost four years, been stranded twice; had changed all four tires; changed fuel pump, tank and sensors; replaced the battery, and the battery clamp and cable, and replaced the passenger seat belt and airbag which was shorted out by the water leaked into the battery chamber in the trunk; fixed oil leak on the oil filter housing gasket, and counting. Paying almost $70k for this car I Do expect it to be more durable. As I would not expect a $100.00 suit to last as a $500 suit so I except 553i to be more durable than a $30k's.Update:The MOST disappointing is the trade in value was just $10,000 was all the dealer paid what a useless 535-BMW. Never Again will I make the same mistake....
