What are all the steps involved in making a car in the factory?

I. Body Shop

2. finished subassemblies are assembled and added to the floor pan and motor compartment.

3. at this point you have the rough shape of a car, but still lack the external body panels that make it look like the final product, lack a roof, and have none of the swing metal parts: doors, hood, deck lid (what you call a trunk/ boot in an automotive factory)

4. In one of the more complex operations in the body shop the body sides are placed onto the vehicle.  This is typically the largest single piece of sheet metal used in a vehicle.  Here's an example of one:

5. Roof time. 

6. Swing metal time.  

7. Hoods and deck-lids are placed in a similar manner to doors.  

8. At this point the BIW looks like a car without wheels, a chassis, a motor, or an interior.  But it's the right shape. Before moving on there's a final section of the production line called "body finishing".  Imagine a tunnel of fluorescent light fixtures with cars running down its center and people on both side of the assembly line at 20' intervals.  The purpose is to identify and fix any problems or defects that would show up once painted.  Workers sand and smooth the body panels to ensure no problems occur once painted.  It's far easier to fix things at this point then to remove paint.

9. Transfer to paint shop.
