Normally, I'd save first episodes for the first of the month, but I couldn't pass up this two-for-one special.
I think I had one of these two Motormouse & Autocat shorts up before, then had to take it down when it was deleted by YouTube. Well, right now, let's scope the opener, "Wheelin' & Dealin'", which sets the tone for this Tom & Jerry clone on wheels. Then, in "Party Crasher" (title card deleted), Autocat (Marty Ingels) intercepts Motormouse's lost shopping list, not knowing the little guy's planning something for his nemesis.
The closing music at the end of "Wheelin' & Dealin'" would be recycled for other H-B series, including Josie & the Pussycats and, of course, Scooby-Doo.
