If I was to go by MatPat's insect theory, I would say the the "car" babies would be artificially grown (the cars possibly real definition of manufactured) in "manufacturing" factories and they could change the embryo's DNA to make it look like a specific car based on how rich the parents are. Like for example, if the parents were very poor, the embryo's DNA would be changed to turn it into a poor "model" like an AMC Pacer. Or if the parents are rich enough, their child could be a high quality "model" like a Range Rover, OR, if the parent have more than enough money, the could decide what their child could look like, this would probably explain why Lightning Mcqueen is the only one of his design.
