What does ltd XL on a 1989 crown Victoria mean?

Answer 1

The LTD part is just the name of the car, it doesn't mean anything special. Pre-1983, Ford called this car the "LTD." From 1983 to 1991 the name became the "LTD Crown Victoria." Then starting in 1992 it was just called the "Crown Victoria."

If it is an LX model (not xl, I don't know what that means), the VIN code should include P74. That denotes that the car was the optioned-out version, not the base model and not a fleet model.
