Terminators are just the code name for the development of the 2003 and 2004 Cobra
Mustang by SVT
. (All 93+ Cobras are developed by SVT and all are SVT Cobras).
Just a term to separate them from the 99-01 Cobras which are not nearly the same or as powerful.
Want to read a great book on them, purchase Iron Fist, Lead Foot.
