Everything about the Ford Taurus breaks at random times, regardless... My mom has owned three of them, each and every one had problems with the brakes, transmission and the newest one has the worst stereo i've ever heard in a new car. As for the Crown Vic needing a different motor, that needed to be done as soon as they switched from the 5.0 to the 4.6. It is as well built as it can be with the cheap parts it is made of. For example, you can't put nitrous on it because the piston rods will break. The tranny's are decent on them, but not the strongest by far. Generally made for as little money as possible, but very reliable, with plenty of room for subs.
