Ford Mustang GT3 / Northamerican GT Customer Programms

[GT-Eins]

Regarding the recently announced Ford Mustang GT3-programme I considered that I am not aware of some facts - maybe one of the experts here in this Forum can bring some light onto this..

Ford announced that they intend to build 40-70 chassis from their latest customer-sports model in the coming years

That sounds good but is still some figures away from the numbers of e.g. the german manufacturers which are in the 3 digit range.

In the past there were quite some GTE / GT3 / GT4-Programmes from Northamerican Manufacturers. But I admit that I´m not aware of how many chassis have been build from them:

GTE/GTLM:
Ford GT
Corvette GTE
Viper GT2
Panoz GT2

GT3:
Ford Mustang FR500
Ford GT Matech
Cadillac GT3

GT4:
Ford Mustang
Panoz GT4
Saleen GT4
Camaro GT4
Dodge GT4

(I´m sure I missed several programs so feel free to complete the list)

Does anyone know how many chassis of each Model have been build or sold? Especially of the new GT4-programmes I have no clue!

Thanks in advance for any helpful data!
