sorry to hear that the GTR was stolen .. unfortunately, they're desirable cars and worth a bit of coin, so people are always going to try and take them.
In my mind, if you cannot afford the insurance, you can't afford the car. If nobody will insure you, then wait till someone will.
This guy obviously didn't want to wait, and paid the ultimate price. He's probably sort of well off anyway, if the car was under any sort of finance, it would of needed to be fully insured.
