Can anyone help me with this here?
So the point of an "SAV" like the X3 is that you take a regular 3 series and you put a bigger body on it so that you have car-like efficiency and performance, but with more storage capacity. This sacrafices sporty performance and looks. The point of the X4 then is to take an x3 and to chop the roof off and give it more sportiness at the cost of storage capacity. To me this seems like doing the equivalent of digging a hole and then filling it back up with earth again.
Clean cars are happy cars!
