Vehicle parts pack. Attempt 3.

1. Metal wheel + recipe.
2. Chitin vehicle armor + recipe.
3. Bone vehicle armor + recipe.
4. Add tiny storage space to doors. (Typical car doors usually contain
space in which you can put some stuff.)
5. Wooden seat.
6. Wooden spike.
7. Wooden door.
8. Wooden roof.
Future reference: these need to be light_ or dark_ gray.  I've made that mistake once or twice.
