Sad day

[Electronic M]

In your shoes, I'd be tempted to look for another of that generation with a decent body/frame and a blown engine and do a swap...If the rust free one is a taxi or police vehicle swap the interior from yours too.

I was watching a youtube video the other day of a guy that pours a bit of trans fluid into the bottom of the doors and other body panels of his crown vic to keep it rust free.

Might be worth considering having a patch of concrete or ass-fault laid down to park your cars on.
Though even with that winter salt eats cars...I bought my Suburban 4WD as a winter commute car and a swap meet hauler, but I'm tempted to park it during the passable snow and get a 1K beater Jap sedan to feed to the municipal rust monster.
