Hi there, catalysts can fail prematurely if there has been a misfire (i.e. bump start or
failure) - any situation where raw fuel can find its way into the cat where it burns. Also, driving through cold water and causing it to splash onto the hot casing can also cause it to split (along with speed bumps).
These are very fragile indeed.
5 years isn't that unusual, I only owned my Scorpio for a few months - it was bought in 1999 when it was 4 years old, and I needed to replace one of them (my car has 3) - sadly, it was almost double your quote...
As others have already mentioned, shop around, but make sure you are searching by the part number, as you don't want the wrong one for your model.
This job should never be complete - the day I think I've done it all, is the day I resign.
