Hot Wheels reuses castings for years — recoloured, re-wheeled, moved between series. Each combination is its own release, and collectors price them separately. "Which Camaro?" is the entire question.
The axes of a variant
Year and series — the same casting in a mainline year vs a premium series are different animals.
Colour and tampos — first-edition colours and short-run recolours carry premiums.
Wheels — a wheel-type change mid-run quietly creates a scarcer sub-variant.
Base and country stamps — metal vs plastic; Malaysia vs Thailand production runs.
Pinning the exact release
The reference answer is the community's release tables: every casting's official list of years, colours, wheels and toy numbers. Matching your car's observable details against that list — rather than eyeballing a photo gallery — is how you avoid the classic trap of pricing a common recolour as its rare sibling.
