I'm a new member here and a new resident to Pennsylvania (from Maryland). I have owned my Z4 for quite a number of years and love it. Never had any problems to speak of but now it seems to have acquired a Ghost. It sat outside while I moved in and there was no Ghost. Now that it is in the garage, in the last month, the top has been down three times and once the windows were half lowered. Today, I washed the car outside and the windows lowered to half again. Car turned off, no key in ignition. Got any ideas?? The Ghost is reasonably friendly it seems and I'm about to give it (him/her??) a name. But I'd actually like to find a new home for the Ghost.
