Even if not completed, it can be interesting to have on the site if it has some vehicles worth listing (which can be the case with old Australian production, as I'm not sure that we have a lot of these)
About the time codes, you mean that there is the time hh:mm:ss as overlay in a corner of the picture? Not a big problem as long as the quality of the image still shows the vehicle correctly.
Maybe you can post one or two sample pictures?
