there are two designated jack points:
front is right behind the radiator on the crossmember... should be a raised area of the metal where you can place the hydraulic jack.
rear is in front of the muffler (towards the middle of the car), same type of deal as the front... raised area of metal where you can place the jack. might be a bit of a reach if you have a short handled or short bodied jack.
the jack points that everyone else has mentioned is really only for the emergency jack in your trunk unless you have an adapter. if you use anything else, you will bend the metal at those points. you
CAN put jack stands there, but i really wouldn't recommend that either... again unless you have an adapter. if you're not careful in lowering your car onto the jack stands, the metal there will bend also.
the best places to put jack stands IMO is on the frame rails... these are rectangular looking "rails" about 3 - 4 inches in from the emergency jack points.
