So I was fortunate to find these just now! And I missed a STH NSX by about 15 minutes. There was a guy there who had just emptied the dump bin into his shopping cart and was slowly putting everything back. So I told him what I was looking for and when he found some he handed them to me. Not how I wanted it to work, but what can you do? Anyway, I got some of the Porsches and Nissans, which is what I wanted. Yay!
