My 1er with 7000km - no rattles!
My 2012 Lux had 60 000km - no rattles
My 2013 M Sport 20 000km - no rattles...
The leather is of good quality and afaic the only medium exec interior that even comes close to the 3er is the new C Class.
Have you ever noticed how much the new 3 series weighs? No? Go have a look... You think BMW did that using an anti gravity device? Customers want faster, lighter, cheaper, better, greater and perfect cars all whilst paying less for the products. They dont want the same dynamics as the previous gen car, they want more, they also want more power and all this whilst making less CO2 and using less petrol...
