I remember the original thread, and never disputed your claim you ordered it that way. That said, EO is not an attractive color on the 1969 Camaro. As you stated, and I am going to paraphrase here, your wife wanted a purple Camaro and you made a mistake by choosing this color and it did not look like what she wanted and that's why you sold it so quick.
Not sure why it's selling for so much now other than it's an odd duck. Also, Mecum has a personal interest in driving up the price of odd color Camaros. He owns a Carolina Blue 1969, which is also not a good color on this car.
