Pre-movie Cartoons...?

[Jeweller]

Hi All,

Wondering if anyone can help me find this.... 
My mother-in-law was telling us about a short cartoon she saw yeeeaaaarrrs ago, at a cinema before the main feature. Remember back when they used to play cartoons before the movie started?? Anyway, this particular one apparently had a car, which we're pretty sure was a VW beetle (or at least looked like one), that had a baby car that sprouted a first tooth which was a spark plug... I know...sounds hilarious huh but she would really like to see it again..
Does anyone know of any websites that might have links to some of the old before-the-movie cartoons. I'm guessing it would be 50s or 60s. Have been trying Google searches but found nothing so far. It's a long shot I know, but any help would be much appreciated.

Cheers

This is Tex Avery's "One Cab's Family" (1952).

There is a copy on YouTube.  The spark plug moment is at 2:31.
