I recently upgraded the top on my '99 Boxster from plastic window to glass window and have several parts available:
1. Original top with plastic window, which is in very good condition aside from the rip in the window. The color is black. $80.
2. Original top transmissions (left and right). $100 each.
3. Original top relay. $50.
4. Convertible top motor (new style). $100.
Will sell all the convertible top parts above as a lot for $300. Shipping extra.
Also available:
5. Rear storage compartment in black (one door is not operating, but repairable). $50.
6. Speedster Humps on black (genuine Porsche). Have a few chips and scratches. $250.
