Last episode Marty was working on the MR2 which turns out to be not quite as clean as he first thought. Almost every bolt was seized or rusted, and while the body itself is in reasonable condition just about everything attached to it doesn't work. This episode the fuel tank tank needs to be removed and new coolant hoses installed throughout the car. The MR2 slowly but surely being restored to it's former glory but there's still a lot of work left to do.
