Here is my post apocalyptic overpass diorama. I chose to use the 3.75" terminator figures as they work quite well with the 1/24 scale cars I used, but really you could use Minimates or Walking Dead, whatever fits the bill I suppose. These are plastic car models with REAL rust growing on them. I used liquefied iron filings to grow the rust, so these cars will continue to get more decayed over time.
