* By Model: Thousands upon thousands. Each manufacturer produces numerous models, and many have variations (e.g., different trims, engine options, body styles) within a single model.
* By Make: Hundreds. There are many car manufacturers worldwide, both large and small.
* By Type: Dozens (sedans, SUVs, trucks, coupes, convertibles, etc.). This is a much broader categorization.
Therefore, a precise number is impossible to provide. It would require an incredibly complex and likely impossible-to-complete global inventory of every car model variant ever produced and currently in existence.
