In his third feature-film appearance, Spencer Tracy plays a small-town hotshot named William Donroy, who talks a young married couple, Gilbert and Marilyn Sterling (Lorrin Raker, Sidney Fox), into purchasing an expensive car. At this point, Donroy takes a back seat to the plot proper, as poor Gil and Marilyn suffer mightily for their imprudent purchase. As a culmination to a series of small disasters, the car is smashed up in an accident, and the Sterlings find themselves $5000 in debt. It is up to good old William Donroy to set things right, with the "help" of a dimwitted Swedish janitor (El Brendel). Previously filmed in 1917 and 1923, Six Cylinder Love was based on the popular stage play by William Anthony McGuire.
