Final answer:
Fine Motor Company is strictly liable for any damage caused by defective parts.
Step-by-step explanation:
In the given scenario, Fine Motor Company is the one who would be strictly liable for any damage caused by defective parts.
Strict liability refers to the legal doctrine that holds a party responsible for damages caused by their product, regardless of fault or negligence. In this case, Fine Motor Company is responsible because they are the ones who put the defective parts in their vehicles without changing their composition.
General Mechanix, as the supplier of the parts, may also have some liability, but it would usually fall under product liability laws rather than strict liability.
