The Ford Crown Victoria was first introduced as a luxury trim package on Ford LTD's in 1981. It became it's own model in 1983 and became very popular with Senior Citizens, Police, Taxi companies, and other fleet use. The boxy body style is probably the best ever, and was made until 1991. In 1992 an all new Crown Victoria was offered, which featured round aero styling. It was rounded out even more in 1998 (it's last restyle), and by the 2000's the full size RWD sedan had completly fallen out of favor. Majority of sales were for fleet and police use, and the Crown Victoria was discontinued in 2011.
Ford's making a huge mistake discontinuing the Ford Crown Victoria. Cabbies and Police need a large car like that.
