Ok! Now we have one big body of our car. But we want to break it in more so
we can get our front separated from the rest.
Then we select the body of the car and we edit it with the Bezier reshape tool.
So our point shows up.
We decide where we are going to split the car and right there we add a new line
of bezier points. Select the tool indicated in red and while pressing Alt for
PC and control for MAC(this means making a copy)drag the mouse in this case
vertically where we want to add an extra lines of points(vertically if we wan
to add a line of points vertically)or(Horizontally if we wan to add a line of
points horizontally).
Once we get that extra line of points we have to know that this is the line
where we are going to split the car in order to get our front and our rest of
the car). Now we need to copy the body of the car(copy by draging and make an
UNDO. This way you get a copy in the exact position as the original)

One of this copy is going to be our front so we will delete the extra points,
and the second copy will be the rest of the car so we will also delete the extra
points as well.
We edit one of these parts and we select the first line of points we want to
delete
(it is not possible to delete all the extra points at once,it can only be done
line by line)We aware of not deleting the point were the to surfaces are supposed
to meet. Select then the next line of points and delete them.
Now we have or front
Lets do the same with the second surface(the rear of the car)but before lets
give another color(blue) to differentiate one part from the other.
It might be confusing but we have to have very clearly that we have right now
two surfaces. One is in blue and is our front while the other one is red and
is our rear. This last one has extra points that we need to delete.
Selecting our fist line of our second surface and we delete it.
Select the second line of extra points and delete it.
Now we have two surfaces that they form the car´s body. Now they can be
edited, textured and so on separately.
