What's the answer to the crossword puzzle clue in "Cardiac Arrest" by the 80's ska group Madness?

Question

From Madness's song, "Cardiac Arrest":

Think of seven letters
Begin and end with "c"
Like a big American car
But misspelled with a "d".

Presumably it isn't Cadilac, since that's correctly spelled with a d.

Answer 1

That might be a CLASSIC car. Another 7 letter word with a D is CARDIAC (probably very intentional). Other C*****C words are comedic, chaotic, caloric, caustic, and centric. Presumably, the mistaken D entered into the string adds to his emotional state when he suffers cardiac arrest.
