What's the Connection Between Abbott & Costello and Crosley?

What is the likelihood that the comedy team of Abbott & Costello would choose Crosley's as cars for two of their movies?

Well...if you take a look at the Internet Movie Cars Database, you can find the two Crosley's that Bud and Lou drove. (A 1940 Crosley Parkway was featured in the 1945 film, "Abbott and Costello in Hollywood," an MGM film tracking the antics of two barbers who become Hollywood agents -- and a 1949 Crosley Wagon shows up in the 1949 film, "Africa Screams," a Universal film that puts Bud and Lou on safari in Africa.)

Coincidence -- or an early example of product placement?
