The mirror wouldn't be good as CCTV but it'd still be better than nothing. I'm imagining that Woolie's argument against your fiancée's suggestion is the cost of setting up and maintaining CCTV, so perhaps they would be willing to consider a cheaper alternative. <shrug> Or maybe set up a fake camera? I dunno. <shrug> I suppose another choice might be to install one of those sensitive car alarms that go off when someone touches the car... but they can be so annoying cos they're prone to being accidentally triggered (and people soon learn to ignore alarms that "cry wolf"). But in terms of alerting your fiancée while she's at work it might work.

Gawd... this reminds me of the first school I taught at in a rather shabby part of Western Sydney. I lost all my hubcaps! Another teacher had his new car _buried_ in dirt. Our Principal once told us at a staff meeting _not_ to bring our good car to school (which doesn't work when you only have one car! :/)
