Perhaps it is all just a misprint ?

I used to collect much of the same literature as Aerohead.
I had a sales brochure from Saturn that had the Cd figures for their cars and remember being puzzled at how that the Saturn station wagons had the same Cd as the SC-2 .
( it was either the SC-1 or the SC-2 . I can't remember after all these years. )
