The Ferrari 250 GTO was once known for being a no-compromises machine that was faster than just about everything else. Today it's mostly known for having a strong habit of setting auction records. The last time one of these was sold, it went for $52 MILLION DOLLARS. There are some car manufactuers that you could buy for less than that.
Now another one is hitting the blocks at the Quail, and there's no reserve at all. That said, don't expect it to be a bargain.
