When Jeremy and Richard are chatting in front of the Formula Easter cars you can see James' Crosley parked in the garage. According to the storyline, he had not yet arrived at the race track.
When James makes modifications for Richard's and Jeremy's car the second time, he installs an audio which is plays when Richard puts his car's roof back up. They say this audio is in Slovakian, but it's in Hungarian.
At the beginning scene where they are pointing at the map, all the close-up shots of their hands are women's hands covered with jewelry and nail polish.
This is clearly done intentionally for comedic value.
