The first DeltaWing DWC13 coupe has still yet to find a buyer nine months after it was originally offered for sale.

Chassis 001, which was pushed into service at the combined ALMS/WEC round at Circuit of The Americas in 2013, was made available for $375,000 on February 15 by the Don Panoz-owned company, and despite having no takers, the turbocharged four-cylinder coupe is making the rounds again in November at the same price.

As a prototype that conforms to its own ruleset, the DWC13 is no longer eligible for use in IMSA, nor is it an option for the WEC or any other major sports car series, but with the proliferation of modern cars taking part in vintage competition, the DeltaWing coupe could serve as the most unique chassis in amateur racing.

Prior to Chassis 002 and 003 coming online, the 1360-pound 001 was driven by Katherine Legge, Andy Meyrick, Memo Rojas, Indy 500 winner Alexander Rossi, and Gabby Chaves in more than a dozen races before it was retired.

Originally presented in chrome, 001 has been finished in the “God Bless America” livery DeltaWing used during 2016, the final season for the DWC13 project.
