How do you get a 2000 Mitsubishi Lancer Evolution VI TME in forza 2?

The 2000 Evo VI TME in Forza 2 is a "unicorn" car meaning it is extremely rare. So rare in fact it can only be won in the auction house when Turn 10 puts one up for sale, it CAN NOT be unlocked by any means in normal game play, you most have the winning bid.
