Did it on purpose, Keith. I don't always follow the rules, even if I should but I am glad you had fun with the image...the title mocked Ford's early reputation for being dead and making tow company's rich and I wanted it to look real dead. I probably had to do as much work to get it to look like that as you did making it look "normal."
I did three different "Darks" channels, two to Multiply and one to Screen and then one Light Lights to multiply to knock down the remaining highlights. To give it a bit more depth, I did a NIK SEP2 contrast selection and changed the blend mode to luminosity.
