I consider the engine.
Stock is stock engine, numbers matching or not, no upgrades.
When I ask if a car is stock and they say no, "i got an aftermarket stereo in it" I laugh at them.(and have done)
When it really matters the term is "numbers matching" IE as the car came off the dealership. RPO codes, VINs, etc
And useing the term "option delete" is a fancy way of saying "no it didn't come with A/C" as in a way of trying to hype up thier lower cost car.
"a stock car you are only leasing time on it, it's not yours untill you mod it"
