2014 BMW 3 Series Diesel 328d 4dr Sedan (2.0L 4cyl Turbodiesel 8A)
So far, so very, very good
 I shopped for 3 years and test drove several cars before deciding on the BMW 328d. I've had the car for a month and I am so impressed with every aspect of it. I have a typical long commute in San Diego - early morning to beat the rush, and a slog in the afternoon. So far close to 39 mpg and >500 miles/tank. Highway mileage is well above the 45 estimated. Car is so sweet and fun to drive. Got the Nav, which comes with a host of other stuff and I say worth the extra $$. For me, this was a momentous upgrade from a reliable 2003 Accord V6 with 145K miles. I highly recommend it to anyone interested in a high mpg, mid-level luxury car. In addition, BMW of Escondido treated me very, very well!
