Fun with math
Let's see.....57086 Javelins and AMX's built in 72/73 and only 4152 of them were Pierre Cardin models.....7.2% of total production.
Only 1420 401 powered AMX's built in 1973 and just for argument's sake let's say 7.2% were Pierre cardin models.............102 in total.
Purely speculation of course but it's probably a pretty rare piece in the grand scheme of production numbers.
72 Javelin SST 258 6cyl. (Parts car)
73 AMX 401/auto/PC
