My first instinct was to lock myself in the garage with the car running, but...
Some suggestions:
Get a better video transfer method, use a signal splitter/tv recorder adaptor - most things are better than filming the screen with a camera at an angle
Get a better video editor, at least refrain from using all the stock effects in windows movie maker
It's "their first montage" not "there"
Also you could choose a song that's better to sync the video to, and maybe ease the fade out so the song/video doesn't just stop instantly.
Some of the shots themself were pretty nice though
