This is the Mini-Exotics kit from 1998 and it was good. The so called sucker car was one of Jim Hall's (maybe with GM assistance) great ideas.
A case of function over form as aerodynamics not styling was important. Skirts and fans were pretty visionary for 1970. I never saw Chaparrals race as the Canadian Can-Am was the first race of the season so cars not ready.
However I have a couple of books plus we can see videos. Jim Hall was one of the great innovators and a good driver in his day.
Thanks for looking.
