BMW Z4 35i auto insurance costs wallpaper review
This all-new BMW Z4, complete with a folding metal roof for the first time, is 100kg heavier than the last one. Some of that is down to extra
safety kit, better materials, the heavy strengthening stuff to give increased torsional rigidity (which is up by a quarter over the last Z) - all the usual improvements you get from one generation of car to the next. But most of it is down to that roof and all the associated mechanisms.
