Back in the day I did a paper on Mustangs vs. F-bodies... this was from my research on the paper, the numbers came from all good sources. This will answer your question as to how many Mustangs to F-body ratio there is
Firebird/Formula/Trans Am/WS6/Firehawk/CETA:
1998 - 32,155
1999 - 32,209
2000 - 31,826
2001 - 21,436
2002 - 30,690
Camaro/RS/SS/Z28:
1998 - 48,490
1999 - 42,098
2000 - 45,417
2001 - 29,009
2002 - 42,098
Mustang/GT/Cobra
1998 - 179,296
1999 - 141,790
2000 - 207,188
2001 - 167,995 (including billet editions)
2002 - 142,504
2003 - 176,362 (including mach1)
2004 - 154,793 (including mach1)
The number of mustangs is QUITE astounding. My conclusion was that Mustangs are chick cars
