All I remember clearly was loving Penelope Pitstop and Muttley, yet I did wish Penelope didn't yell so much. Ah, pre-feminist awareness!
Yeah, some racers tried dirty tricks to get ahead, but the show had stricter limits then, and made sure that justice happened even if fairness didn't win out at the finish line.
Still, the wordplay and backgrounds were chock full of gags and jokes, pointedly current and timesless jumbled together in a crazy stew of humor that never really stopped. If you missed one joke there were plenty comin' to go for!
With age the gags are probably easier to get and adds a layer to the funny, no doubt.
I recommend this series because it's just funny.
