The problem of catalytic converter theft has raised it's ugly head in my area. I have a 2004 X5 3.0i, does anyone have any idea if this model is vunerable to theft, obviously ground clearance is good but not sure how easy the cat is to get at. The local police say the removal can often be done in less than 90sec. on some cars. I am considering parking over a raised concrete slab but this will be difficult and wonder if needed. Anyone any ideas on vunerability of the X5 cat?
