Granted, it's an older car but you shouldn't have to replace the intake manifold for $1000 because it is made of a cheap material. Why did fleet cars get warranty coverage on this and personal owners didn't? Headliner is falling down, ball joints were shot, plastic door handle snapped off, plastic cover fell from above onto the driver's feet. Now we have a leak somewhere causing the floor to be swamped with every rain. Overall, mechanically pretty sound but body interior and exterior quality is very poor. Especially for a luxury car. Ford was really milking this cash cow when they sold this junker in 1997.
Power + mass = safety.
Stop using cheap plastic parts that disintegrate. Ford had a solid car but chose to let quality slide.
