http://www.318ti.org/forum/showthread.php?t=31219 "As promised from a previous forum thread, the following data came from "Standard Catalog of Imported Cars 1946-2002, 2nd Edition":
1995 - 7238
1996 - 7238
1997 - 4622
1988 - 3735
1999 - 656
I also have how many models (Base, Active, Sport and Clubsport) were exported to NA by model year. This information will be updated to this thread shorty."
My calculator totals that to 23,489.
