Hi, all I Have just bought my first bmw and its an E61 520d . It is a 2005 with 40 thousand miles. Its the SE model moon stone grey with business pack upgrade, black leather and has the 17inch wheels. One thing that is niggling me is that the boot window keeps popping open just as I start the car up? Why would this be and who can shed some light on this. Apart from this the car has just had a K&N filter put in and drives great, the bm is a very nice place to be compared to my last car, and handles better than expected for a large car. Ps This forum is great and I have learned quite a lot from it so far.
