The internet describes the car as both Tangoreen and Tangogreen. I really think it should be TangoGreen. If you trying to make an orange color be enviro-friendly, wouldn't you put the word "green" in it?
This puzzle has been all about missing letters. Nobody ever typed "Circuit", it was "Circut". And now "Tangoreen" was answered, when my answer is "TangoGreen". I awarded the point anyway, was tired of waiting.
