2015 BMW 3-Series Seat Room and Comfort: Pros
Year	Comment
2014	The BMW 3-Series used to be tight inside, but it has grown with each redesign, especially the most recent one. The rear seat of the current sedan isn't nearly as roomy as that in the related 3-Series Gran Turismo hatchback. But it offers considerably more rear legroom than direct competitors like the Audi A4, Cadillac ATS, and Mercedes-Benz C-Class. In fact, combined front and rear legroom is the same as in the one size-class up, ten-inch-longer Mercedes E-Class. (You do get a half-inch more rear headroom and nearly two inches more rear shoulder room in the Benz.) Beyond the specs, the BMW's rear seat is comfortably high off the floor, a rarity in the age of sedans with plunging coupe-like roof lines. see full BMW 3-Series review

2015 BMW 3-Series Powertrain: Pros
Year	Comment
2016	With at least 320 horsepower (BMW tends to under-rate its engines) to motivate its 3,800 pounds, the 340i is very quick. Even with a manual transmission--a disadvantage these days if you care only about the quickest time--the 340i xDrive can rocket from a dead stop to 60 mph in under five seconds. But so can the Jaguar XE, the Mercedes-AMG C43, the Infiniti Q50 Red Sport, and so on. All of these cars with supercharged or turbocharged six-cylinder engines can accelerate so quickly that it's hard to justify the even more powerful engines of the BMW M3, Cadillac ATS-V, and Mercedes-AMG C63 for driving on public roads. (The unboosted V6s from Cadillac and Lexus lag behind the others.) Those who feel the need for a little more thrust than the regular 340i offers can now purchase a 35-horsepower bump for $3,195. This "M Performance and Sound" option also includes a freer flowing and likely more throaty exhaust. Even without this option BMW's new six-cylinder engine sounds sweeter than the old one, with the singing of sophisticated machinery at high rpm and an occasional snap and crackle from the exhaust (now lower in tone). Your ears will enjoy exercising it. The Jaguar's engine makes more noise, but of a less pleasant quality. The manual shifter is typical BMW: smooth and reasonably precise, but with a less mechanical feel than I personally prefer. see full BMW 3-Series review
