2009 BMW 3 Series 335d 4dr Sedan (3.0L 6cyl Turbodiesel 6A)
I have been driving BMWs for over 30 years and when the 335d was released I waited for a couple years and then pulled the trigger.
I couldn't be more pleased.
I use this car as a daily driver on a 60 mile round trip commute.
I am averaging between 32 and 34 mpg.
The acceleration is on par with my 335i convertible but the low end torque is awesome.
The car handles very well and does provide comfortable seating for 4 adults. My wife cannot believe it is a diesel.
There is almost no diesel noise inside the car except at idle with the radio and HVAC off.
At highway speeds you would never know you are driving a diesel.
There is absolutely no smoke and no smell.
