trading the extra two gears, fuel economy, and great steering is worth the 2 cylinders. also, if the 28i is good enough for the germans then it should be good enough for me. so i think that the 28i is just fine, and i regret nothing because i got my 2014 X1 xDrive 28i (alpine white with red leather) with every option available except the servotronic, it is in my moms X3 35i and it feels numb, relatively, of course
