I don't know if you could actually drive these on, say, nearby I 55. The license plate in the top photo does not look like it has been valid in the State of Illinois since 1923 and using a Jack Daniels box as a trunk might attract the attention of the police. The Shelby Cobra, below, might be okay if the muffler meets government regulations.
It's not Phoenix, of course, but most people here are hiding out this week. The forecast is for high temperatures of 100 - 102 F / 38 - 39 C for the next four days. We've seen hotter in STL (the highest I remember is 106 F / 41 C) but, as they say, better get used to it.
