Continuity mistake: In episode 1-12: "Clash of the Tritons," in the scene where Veronica is in her trunk, as the camera angle is on the trunk of Veronica's car, the shot right before Wallace lets her out, you can see the reflection on the trunk of Percy Daggs, III. However, the next shot is of Wallace walking up to the car.
Other mistake: Season 1, episode 19, Hot Dogs. After Veronica bugs the Spanish-speaking man who returned the dog in the park, a shot of her laptop is shown. It's the exact same shot as when Veronica was helping the valedictorian front-runner find out who was harassing her. There are books and even the girl she was helping in the shot, proving that the shot was not in Veronica's car, as seen in the very next subsequent shot.
