That's crazy, you have to believe the thief owns a VX, how else would he know those 10 year old parts are so desirable? But of course I'm reminded of when Maximas suddenly sky-rocketed to the top of the most stolen cars list. It took some research before they discovered that the '02+ forward models (IIRC) had bi-xenon lights in the exact same enclosure as the '01 and previous years such that they were literally plug and play. Nissan had the bi-xenon headlights listed for like $900 each and there were no aftermarket options back then, so obviously they became extremely hot on the black market.
Maybe someone has just been watching eBay auctions? If so that's a pretty sophisticated thief.
