YOu can get to the motor in the trunk no prob.

Take off the rear panel, remove the two bolts on the left panel (one is inside the left rear access panel for the shocks) and remove the floor plastic screw.
Then pull the left panel out from the side of the car, it will snap out of place.

Then there is one bolt holding the motor in place, make sure you disconnect all wires going to it (power, antenna) and the wire powering the trunk light.

You can then do whatever you want with it... personally trash the SOB and install a s2k antenna
