Agreed, 100%, the LM is my favorite classic Ferrari (along with the TdF). Speaking of which, the TdF whips the GTO in feel, grip, stability, you name it. All around, it's a more balanced car at speed, though not nearly as powerful. There's a 10" difference in wheelbase length between them, which is not a small amount. Of all the classic Italians I've driven, the TdF seems the most surefooted.
I think classic Ferraris are priced about right, personally. Because they're very limited in quantity and there will never be enough to go around, even among the super rich. I also see it this way, would I rather have a typical Jackson Pollock painting (splatters on canvas) or a 250 LM?
