Dylan, Ash and Jermaine are at the used car lot checking out rides. The salesman is all smiles until they are buckled up ready to go on a test drive and he finds that Dylan only has a learner's permit. After a nervous driving lesson with Dylan, his Dad tells him he'll have to get a job and earn the money for a car. Mike tells Dylan that he used to take the car out on his own to learn to drive before he got a license. Dylan is anxious to drive and asks Mike about using his car when he goes away to college.
Meanwhile, Jermaine is working hard on a school project, trying to make a rocket that will attain an altitude of 3,000 feet. He needs to get some special supplies from a store across town before it closes, so Dylan, with the rest of his family out of town, offers to solve the problem by driving him and Ash over in Mike's car. The three are having a great time despite Dylan's somewhat reckless driving, and they get the special ingredients for Jermaine's rocket fuel. On his next launch attempt, Jermaine's rocket reaches the 3,000 foot goal, then turns downward and heads back to earth, going right through Mike's car windows. Dylan is busted when his family arrives back home before he does.
