Driving Virtual Sales

It's getting to the point where I can't read a technical publication without running into some mention of Second Life! Issue 129 of Web Designer magazine reveals that Mazda has created a concept car for SL residents to test drive. No word yet on whether they will sell the car either in SL or the real world, though.
If such an item were available for purchase in SL, what would it go for? Certainly not the Linden Dollar equaivalent of the real world cost because I can't imagine such a car having the same "value" in a virtual world without all of the physical sensations. Still, it would definitely rate as a premium item, which could lead to some new social side effects. There's so much ruckus about the Grand Theft Auto video game series, imagine it playing out in a virtual world where a car that you essentially paid real dollars for. What would a thief do with it? Pretty much the same he would do in the real world; either sell it, flaunt it (e.g. take his picture with it and post it) and/or demolish it. The last option may even become a form of expression for inhabitants who don't appreciate economic elitism in "their" virtual world.
Also, if a number of such cars are rolling around in SL, how do you identify the rightful owner? Objects have properties that define the creator and owner, but like any software object this information is susceptible to hacking. Maybe a license plaete system would be useful? You can get checked against your license plate to see if the ownership is consistent. Yes, this object cna be hacked too, but if you fake a plate then it won't show up in the DVV (Department of Virtual Vehicles) registry. Just in the real world, if you sell the vehicle, you can officially transfer the plate ownership. Now I just hope we won't have to wait in long lines and take tests to get our licenses renewed...
