According to Jim - Season 2
Jim and Cheryl clash over a digital camera. He deletes a picture she wanted to keep, so she hides the camera from him. Dana needs to buy a new car and Cheryl offers to go with her, but Jim says chicks are no good buying cars by themselves, because they’ll get distracted with other less important things like mirrors or cup holders. Offended, Cheryl is determined to prove Jim wrong and actually gets Dana a car for a fair deal, but the car soon breaks down.
