What can I tell from looking at my USA spec VIN?
A typical RX-7 VIN looks like:
JM1FD3311P0200001
In order, the fields are as follows:
"JM1" "World Manufacturer
Identifier" for Mazda
"FD" RX-7 series
"33" body style
("33" = coupe)
"1" "Misc ID field"
(1993: "1" = US, "2" = Canada.)
(1994: "3" = manual seat belts, 2 airbags)
(1995: "3" = manual seat belts, 2 airbags)
"1" "Check Digit"
(used to verify that a VIN is not bogus)
(calculated for each car)
"P" year model code
(1993 = "P")
(1994 = "R")
(1995 = "S")
(Q was not used)
"0" assembly plant
code ("0" = Hiroshima)
"200001" serial number
(1993: started with 200001)
(1994: started with 300001)
(1995: started with 400001)
