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

    "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)
