1:64 Scale Die-Cast Line

Here's an FAQ.

Did Spark Plug Entertainment ever make these toys?

 * No, because it is a rip-off/mockbuster of Cars, so none were planned to be produced.

Why do these not exist officially?

 * Because they would be way too cheap to be produced based on a low-quality/budget film.

Why did "The Little Cars" franchise get a toy line but not (A) Car's Life?

 * Because The Little Cars in the Great Race spawned a lot, completely over 8 films of over 7 sequels, some PC game, and a musical.
