I would greatly prefer to be offered both (SETF CAR) and CAR. 

Also, consider setf-expansions:

  (defun mycar (x) (car x))
  (defun setmycar (x y) (setf (car x) y))
  (defsetf mycar setmycar)

What should happen in this?

  (setf (my.car *x*) 42)

IMO ideally the user would be presented with all three possibilities
in the XREF buffer, or just MYCAR and the (DEFSETF MYCAR).
