You can jack the car at the front under centre part of lower suspension cross bar. At the back under the rear cross member the rear valance is attached to. In each case a long block of wood will spread the load. With a trolley jack having curved lift plate the underneath of diff can be used as rear jacking point.
On a ramp I use the double skinned parts of chassis just behind engine mounts at front and under the chassis cross rail that rear seat mounts are bolted through just forward of rear wheels.
Variations of these points can be used to jack individual wheels.
If working under car without ramp, axle stands should be used to secure car after jacking.
