IMHO, we should jump to the defsetf form.
Then, moving the point to setmycar, we can jump to the setmycar
definition. In case we move the point to mycar, we can jump to the
mycar definition (if it exists).
This seems consistent behaviour, to me.

If I'm allowed to vote, I vote for presenting just the defsetf because
it's the form that allows you to write (setf (mycar ...) ...) in the
first place. In your example, mycar is also a defined function but,
for defsetf purposes, that's irrelevant. As a result, it shouldn't be
presented as relevant. But that's just my opinion and I will not be
bothered if you choose to implement it the way as you seem to prefer.
