Kim finally manages to get her own car: a literal fixer-upper that her dad once owned. However, chaos ensues when the Tweebs volunteer to trick it out. Meanwhile, Shego gets out of prison by way of Motor Ed and assists in his latest caper.
When Jim and Tim activate "second gear," a hood scoop pops up. However, when Kim's car launches into space, the hood scoop disappears in a couple of shots.
Since this episode is supposed to come before Trading Faces, Bonnie should not make friends with Jim and Tim in that episode, since they ticked her off in this episode. Though it is possible that Bonnie only made friends with them to get the dirt on Kim or get under her skin.
Bonnie's interest in Jim and Tim was always self-serving, either in getting something for herself or in hopes of humiliating Kim. But the only Possible she ever holds a grudge against is Kim, so this behavior is not all that unusual for her, since both instances gave her a chance to make Kim look bad. Which Tim and Jim clearly have no problems in helping Bonnie do, so long as it suits them.
