i love 2 and 5.
2 because of the lighting and the industrial feel to it, and 5 because of its wonderful use of the foreground leading up to the horizon (i'm sure there's a photography term for this, but i won't front
)
since i can only pick one, i voted 5 because of a very very minor nitpick - the placement of the graffiti makes the right of the photo look a bit busy and takes a bit of attention away from the lines of the cars...
