2011 BMW 3 Series Diesel 335d 4dr Sedan (3.0L 6cyl Turbodiesel 6A)
At 140K miles
 Run flat tires and the carbon build up in the exhaust manifold and diesel particulate filter and a front wheel bearing are the only problems thus far.   The torque that the engine puts out keeps the car feeling fun.  No electrical or other problems with the car.  The exhaust manifold was replace under warranty at 80k.  I am about to pull out and have the diesel particular filter cooked at 140k.  The right front wheel bearing was replaced at 140k.  The car has held such little value though and I am told that it values between 6-7k.  It was purchased used in 2013 with 34 thousand miles.
