This was a design study by Virgil Exner of the the great cars of the 20's and 30's. A couple were produced in limited numbers. I beleave these were the Stutz, Mercer, Bugatti, all I can find are pictures of show cars. Other cars in the Renwal series were the Duesenberg, Mercer, Stutz, Jordan Playboy, Bugatti, Pierce Arrow and the Packard.
I hope this explains in little.
