Ok,
at the front of the car, position
the vertices indicated by red dots
as shown below. Make the cut shown
in yellow.
Extrude the polygons shown in the
picture by a value of 1. The actual
value doesn't really matter because
we might move the polygons later.
The
extrusion created extra polys that
you don't want but to be able to see
them, you have to hide the mirrored
half of the mesh. To do this, select
the mirrored half of the car, click
on the "Display" tab and
further down the display panel, click
on the "Hide Selected" button.
Now
at the front of the remaining half,
there is a thin strip of 3 polys that
was created by the extrusion you just
made select all of them and delete
them.
To
make things easier, it might be wiser
to detach the hood from the car first.
So unhide the other half of the mesh,
select all the polys that make up
half the hood and detach them from
the rest of the mesh. Name the hood
polys "Hood" and click OK.
Now hid the remainder of the mesh,
leaving just the hood polys visible.
You
will notice that there is now only
one half of the hood so mirror it
and make sure that you select "Reference"
from the Mirror dialog box. Select
the front row of vertices and move
them backwards a little.
Select
the edges at the bottom of the hood
as shown below.
Change
to the bottom viewport and shift+drag
the selected edges diagonally between
the X and Y directions as shown below.
Adjust the red vertices as shown in
the zoomed in areas.
Continuing
the hood
Select
the two edges shown and extrude them
inwards. Weld the two vertices in
the green circle.
Now
select the remaining edges at the
top of the hood and do the same to
them. Now your hood should have some
depth to it. Now you need to create
the ridge that runs down the middle
of the hood. Create the cuts shown
below.
Select
the new polys shown and extrude them
by a value of 0.7. There will be a
thin line of polys between the two
halves that you must delete or you
will get two ridges on the hood instead
of one.
Now
at the front of the remaining half,
there is a thin strip of 3 polys that
was created by the extrusion you just
made select all of them and delete
them. Now zoom into the left viewport
and get very close to the front of
the hood. You will see two vertices
that were created by your extrusion.
Move these two vertices in the direction
of the green arrows below until they
are on top of the ones below them.
DO NOT WELD THEM! Just leave them
on top of each other.

As
it is now, the edge around the hood
is too round. You have to sharpen
the corners of to hood to make it
look better. Select all the edges
shown in red and chamfer them by a
value of 0.1. Add a "Meshsmooth"
modifier and set the iterations to
2 and look at what the hood now looks
like.
You need to clean up some of the vertices
created by the chamfer. Zoom in on
the left viewport again and you will
notice a triangle of vertices as shown
below. Weld the two vertices in the
red circle.
Select
the edges shown and chamfer them by
0.2. Once again, zoom in on the mesh
in the left viewport and perform any
vertex cleanup that may be necessary.
The
hood is now done so hide the hood
and show the rest of the car.
