With the Gadgetmobile damaged in a high speed chase and considered to be obsolete anyway it's retired from the force and sent to a used car lot where it hangs out with two other former hero sidekick cars from the 50s and 70s. Meanwhile Inspector Gadget (and his replacement Gadgetmobile) is being continually upstaged by new supercop Devon Debonaire and in danger of losing his job if he makes one more blunder. Which he inevitably does but Penny and Brain have suspicions that there's something fishy about Devon and investigate him. (thetvdb.com)
