This was posted in the old Freepository, but I had an email today informing me of an error, and I found that there were two missing files in the version I uploaded to ShareCG; the plate textures for the Chicago Police. If you downloaded this set then you will need to download it again to get the corrected version.
The set is a set of textures and MAT poses for Poser 6 and later, to make my FireStar Sedan into a Police car from one of the following Police forces:
City of Miami Police
Illinois State Police
Metropolitan Police (London, England)
Kent County Constabulary (England)
Thames Valley Police (England)
Toronto Police (Canada)
Royal Canadian Mounted Police
The set is in my ShareCG gallery on this link.
