Well, hey, if the guy has the disposable bux and he WANTS it - what the heck?:shrug
But, speaking for my own darned self (and who asked me anyway?), even if I were worth more than Bill gates I wouldn't be able to see the sense in paying that much for any car. I don't care what doggone car you'd care to mention.
If a California is worth $10 mil I can't imagine what a real GTO would go for if one ever went to the auction block. I passed on one back in the early 80's for what now sounds like a piddly sum.
