By the seller's rationale, a Festiva with a five-speed manual is a valuable classic car because the automatic transmission was invented, like, EIGHTY YEARS AGO!!:

Notice the lovely vacuformed plastic packaging, confirming that this set is indeed from the 1930s.
I don't know why I even have to point this out, but: NO AFFILIATION!!!
