Rambler is counted as AMC and since Jeffery is pre war I decided not to include him, lest I'd be forced to include all the other pre war American cars which would eventually get to the point of ridiculous.
I feel Duesenberg, Saleen (S7 is the reason for suggesting it), SSC, & Shelby (though I've always had a hard time whether to include this myself) should be included.
Updated to add Shelby (considering they made 6 Daytona Coupes, enough to count as a production model), SSC, and Saleen, however I left Dusenberg out because otherwise I'd have to add a few other pre-war ones (Cord, Pierce-Arrow and La Salle come to mind) and I wanted to keep it relatively simple.
