I reckon depends on: how many dents, the concentration of the dents (spread out or together), how deep are the dents, where on the car are they.
My "other car" has the same problems and paintless dent repair was not considered because they were on the roof (at eye level), were very numerous and shallow. In certain light and angle, a dent was there, and then at another angle it wasn't! It was suggested to do the entire roof. There were smaller dents on the bonnet and boot which could be popped out but then those panels will need to be repainted.
