I just learned that Hank died last year at age 99, and his Cobra (CSX 2227) is getting sold at Mecum, just like he predicted. His kids didn't want it at all, but knew it's worth millions, as Hank had been offered 2M, and they'd eventually auction it off

from 15 to 10 years ago, Hank drove his Cobra to a LOT of car shows, little local ones (Simpson's Nursery), and bigger ones like the Knotts Berry Farm Fabulous Fords. If you went to a good sized car show, you probably saw it, and I posted about it a couple of times, as it's a REMARKABLE car, and Hank was a really cool guy!

One of the last original owner Cobras, this is also one of the most raced, as I've thoroughly written about in the above linked articles, Hank entered nearly 400 races, including SCCA, Solo 1, rallies, slaloms, and private club events, and received over 260 trophies and awards.
