2016 BMW 3 Series Sedan 340i 4dr Sedan (3.0L 6cyl Turbo 8A)
Best 3 series, under M3
 I have own and driven my BMWs such as 740i,745i, M3s. I was going for M3 but settled on 340i. Its fast as previous e92 M3. BMW claims 0-60 between 4.6-4.8.I have my 340i loaded with all the options and its worth it. I test drove 320i and 328i but I went with 340i. It has 320hp with 330lb.ft torque and can keep up with many cars on the road. I really love driving it in Sport or Sport+ mode, plus exhaust is more deeper and fun. I will recommend 340i or 340ix and its one step below M3. Plus you save $15-20K.
