We had to fix a lot of stuff here.

Please make sure not to create duplicate address points, do not duplicate the same information on buildings and nodes, and if a car dealer sells multiple brands, there is only *one* node on OSM and not one per brand.  Use the "brand" tag correctly to store the list of brands (not in the public name).

You will find a corrected version here:
