Car appreciation... the aesthetics, the engineering, etc

Depend on damage done while cutting out the cat.

Are you intending to do the work yourself or pay someone?

I have collected two Toyota Prius from different owners that were each targeted twice for the cats. Neither owner wanted the expense of a catloc on the first occasion but both wanted one after lightening had struck twice. I don't know how good catloc is in resisting attack but if you have one fitted it makes your cat less desirable than an unprotected one down the road.
Two other Auris were attacked in one street five doors apart at the same time. It is so common however I don't think we've had anything in that had legitimate protection fitted.
