How rare are manual transmission LP640s and LP670s in the United States?

I recently sold a 2008 Lamborghini Murcielago LP640 with the increasingly desirable manual transmission. We all know that the later Murci’s with a stick are rare but I was curious just how rare. Here is a list of the US cars, best I can tell. I have counted 26 cars. 9 of them were exported, salvaged, lemon lawed, have had serious accidents, or were used for press appearances. If you have info on any other elusive 3 pedal, true 6 speed manual cars with this so-called proper gearbox please let me know. They are displayed below by VIN, Year, Coupe/Roadster, and exterior color.
