I like the 1965-1971 fastbacks the BEST ( I like all mustangs, even the number 2's)... Next I like the jelly bean 1994-1998, because it has very good looking lines, and they just look better than the new edges... aptly nicknamed the Box Edges... for endured fugliness... unlike the Fox-Body which pulled off the nickname BOX-body much better. Would I ever own a Box Edge? Like the 03-04 Box Edge Cobra? Of course I would, but there are plenty of other cars that I'd rather have... Like a 1967-1970 GT-500, or 2007 up GT500... or better yet... A 1996 SVT Cobra, with a 03-04 Box-Edge Cobra drivetrain... Yet EVEN better a 1994-1998 V6 mustang with a SOHC Ford 427 cammer swap, tiny 3 spokes, single exhaust, and sideways cobra emblems for added sleeperness/fugly ricerness.
I believe that the Fox chassis was originally named the BOX chassis... but someone thought that was offensive so they changed it to Fox.
Of course I like cars with Jelly Bean/ Tear drop designs, because in the end, those are the more aerodynamic/ better looking... Ala GT40, Shelby Daytona Coupe, Ferrari F430, Saleen S7, Saleen S351 (94-98), 1949 Ford, and the regular 1994-1998 mustang.
PS: I do like the Box Body, but the only reason I don't have one is that it has the aerodynamics/ styling of a brick/ cardboard box...
