Everyone wants one, one day that seems to be the general comment.
They arent like 150K you can pick them up quite reasonably, so if you want one buy one and stop mess about.
Personally I looked at a new 7 a few years back and preferred my car but that was down to personal choice.
Swapping a car because other people have brought the same car is laughable to me, if its really that important then get a kit and build your own.
