HI mate!
come stai? ;-)
The chassis number for a Mazda familia (323) GTR always start with BG83J***
this how she calls herself if you prefer.
The factory car name is BG8Z, this is how mazda call her
this name covers the GTR and the GTX from 91 to 94, the number which follows determinate if its a GTR or a GTX (to 300000 its a GTR, from 3000001 its a GTX)
The pet name of the car is Familia (or 323), this how the maz shops call it
Titine is how I call her... but we dont care!
however, i dont know how to find out the production number of the cars...
as i can remenber, some one told me a long time ago... but im not sure.
i dont think japanese models got one, maybe its just for export...
'hope this helps!
im gonna try to find more!
i just realized your also on 323GTX's forum
