It's easy for the mass media to say "most expensive" and possibly it is as (maybe?)those cars are worth more in Japan.
however, here in the States you can regularly get 355's and 360's in the $65-$80k range and I recently looked at a 14k mile Testarossa for $65k.
I think more disastrous was that freight train in California a few years back that hit the transporter carrying several vintage Porsche speedsters and 356's. I can find a link if you've never seen that one before.
