Years ago when I was a detailer at Northland Chrysler we had the service contract for the R.C.M.P. To keep them happy we installed cheap stereos and gave them a courtesy clean in and out. I have first hand knowledge as to why they were called "pigs" Messy cars! Did find a few interesting things shoved into the backseats sometimes though--only time I tried Thai stick. Oh yeah, once I backed a Diplomat cruiser into a Mercedes taking it outside. The Diplomats were dogs but the Impalas would lay 40 feet of rubber.....or so I "heard". CHEERS.
