2015 BMW 3 Series Diesel 328d 4dr Sedan (2.0L 4cyl Turbodiesel 8A)
buy a BMW diesel as soon as you can
 I got my 328d used with 34k miles. I've put 10k miles on it in the last 6 months. I drive a lot for my work and getting something fun with great gas milage was my goal. I've owed BMW before (2008 335xi) and have owned a number of luxury class vehicles in my day. I traded a 2016 Lexus 350is f sport for this car. Day to day i average 36.5 mpg. I normally get about 520 miles from a tank of gas with about 1/8 tank left at time of fill up. On long highway trips i can get 50.4 miles to the gallon. I live in so. cal so lots of hills and traffic. I couldn't be happier with this car. It's got a lot of pep. It's not a rocket ship but it's got plenty of umph and i rarely miss my faster cars. The M-sport package is a must. It really adds an edge to daily driving. I like to drive a little more aggressively than most daily drivers and the low end grunt brings a smile to my face every time i pull away from a stop. It cruses at 80 mph at just under 2000 rpm.  i have to warn you, i did have a fuel injector go bad on me. but they are covered under the EPA for 10 years from purchase date and mine was replaced at no charge. If you buy BMW i strongly suggest CPO. Fixing anything on BMW can be very expensive. With that in mind. this is a fantastic car. One more word of wisdom. don't buy a bmw diesel older than 2013. There was a problem with the timing chains and it causes catastrophic mechanical failure if it breaks. Look up the vin number and make sure it has a "W" in the engine code. Most from 2014 and all (from my understanding) from 2015 on have the W engine. Buy it, drive it, laugh every time you see people buying gas.
