An extendable vehicle jack includes a horizontal frame having a rear section with a front section extendable therefrom. Within the front section is a lifting mechanism including a plate that engages the lower surface of the vehicle as it is being raised and lowered. The lifting mechanism includes a hydraulic pump and cylinder that expand and contract a scissors jack. The front section is automatically extended from the rear section with either a hydraulic or pneumatic cylinder. Accordingly, a worker can position the lifting mechanism any desired location beneath the vehicle frame.
