For series, I will repeat my suggestion here.

list the movie name as: name (year, episode)
List IMDB number the same for all.

We would end up with one page per episode. It may result in some cars being listed twice but on different pages (same car in different episodes) but that would probably be OK or a reference could be placed in the episode comments to refer to the other page.

That should separate the large pages that result from series and should be no problem for search. Also, I don't think it would require modification of the site.
