1. A stackable car dolly, comprising: a frame having a supporting portion and a tire receiving portion; the supporting portion supporting the tire receiving portion and having a plurality of wheel acceptance areas; the tire receiving portion comprising a pair of angled inner walls and a pair of outer walls;a pair of rotatable arms; anda reversible saddle having a frame rail member and a pinch weld member opposing the frame rail member;wherein, in an extended configuration, each rotatable arm extends above the frame at an angle; andwherein, in a retracted configuration, each rotatable arm extends underneath the frame. 2. The stackable car dolly of claim 1, further comprising a pair of holding portions; each holding portion being adjacent one of said pair of outer walls. 3. The stackable car dolly of claim 1, wherein the supporting portion comprises four rectangular plates. 4. The stackable car dolly of claim 1, wherein the saddle is removably coupled to each rotatable arm with at least one locking member. 5. The stackable car dolly of claim 4, wherein the locking member is a clevis pin. 6. The stackable car dolly of claim 1, wherein the saddle has two outer channels and two inner channels; each channel being configured for the passage of a locking member. 7. The stackable car dolly of claim 1, further comprising four casters secured to the supporting portion. 8. A method of placing a dolly from an extended position to a retracted position, the method comprising steps: providing the dolly, the dolly comprising: a frame having a supporting portion and a tire receiving portion;a first rotatable arm and a second rotatable arm;a first holding portion and a second holding portion; the first rotatable arm being pivotably connected to the first holding portion; the second rotatable arm being pivotably connected to the second holding portion; anda reversible saddle;uncoupling each of the first rotatable arm and the second rotatable arm from the saddle;causing each of the first rotatable arm and the second rotatable arm to rotate underneath the frame; andusing at least one locking member to lock with respect to the frame each of the first rotatable arm, the second rotatable arm, and the saddle. 9. The method of claim 8, wherein at least one said locking member is a clevis pin. 10. The method of claim 9, further comprising the step of stacking the dolly atop another dolly. 11. The method of claim 8, further comprising the step of stacking the dolly atop another dolly. 12. The method of claim 8, wherein the tire receiving portion further comprises stop walls. 13. The method of claim 8, wherein the saddle has a pinch weld member and a frame rail member. 14. The method of claim 13 wherein, in the retracted configuration, the pinch weld member faces away from the frame. 15. A car dolly, comprising: a frame having a supporting portion and a tire receiving portion; the supporting portion having a plurality of wheel acceptance areas; the tire receiving portion comprising a pair of angled inner walls and a pair of outer walls;a pair of rotatable arms; anda reversible saddle;wherein, in an extended configuration, each rotatable arm extends above the frame at an angle; andwherein, in a retracted configuration, each rotatable arm extends generally horizontally underneath the frame. 16. The car dolly of claim 15, wherein the saddle has a frame rail member and a pinch weld member opposing the frame rail member. 17. The car dolly of claim 15, further comprising a pair of holding portions, each of said pair or rotatable arms being pivotally coupled to one of said pair of holding portions. 18. The car dolly of claim 15, wherein the tire receiving portion is M-shaped. 19. The car dolly of claim 15, wherein a plurality of channels extend through each of said pair of rotatable arms. 20. The car dolly of claim 15, wherein each wheel acceptance area comprises two walls having a gap therebetween.
