 Biggest upside is the interior room for a 3 series and performance. Good gas mileage, speed when needed and BMW quality all around. If there was one fault is the interior is 3 series Spartan ! Not luxurious as a 4,5 or 7 series. But hands-down the most practical of BMW wagons or SUVs ! Awesome for BMW to make so many new models in 2014 ! Thanks BMW
