These crown-vics are junk posts are about as bad as the guys at work that rag on the Escape's they used to drive. After driving the replacement Jeeps for a month and all the window tracks broke allowing the windows to be in open position in the middle of January the tune was changed. That was just one problem. Had the Escapes 4yr and 150k (probably 400k with idle time) just normal repairs. No automobile is meant to run 24x7.. even in security roles it'll wear them out.. usually Ford's last the longest. Chevy and Jeep well won't go there. Just my view.
