Yes.  What you must do to keep the car through a Chapter 7 varies depending on whether there is non exempt equity in the car.
If there is no equity in the car, after subtracting any car loan and exemption from the car's present sale value, the bankruptcy trustee will not take the car. 
If there is equity in the car over and above the value of the exemptions available, a debtor can usually buy any unprotected equity from the Chapter 7 trustee.
