perl · Answer

so each car has a vin number, its some 9 digit number of whatever. and it is unique

perl · Answer

so there is a function between vin number and models. 
how about the other way around

perl · Answer

there exists a function between vin numbers and car models.
is there a function from car models to vin numbers?
