Surprise! I was out walking and that car was out from under the car cover, and it's got a brilliant license plate... and I met the owner

 He told me that his wife came up with the license plate, as every other possible Shelby vanity plate idea has been used. I like it. 

found a couple days ago, with the car cover on https://justacarguy.blogspot.com/2022/04/seen-on-todays-walk-around-neighborhood.html

I'm no expert on Cobra Daytonas, but I don't think I ever saw one with the AC badge on it.
