When we bought the GT1, I did NOT want a sun roof.  The Potniac store found a black GT1 with all of the goodies we wanted in about five days that included a sun roof (headed for San Francisco).  With $500.00 good faith money paid, the car was shipped to Southern California.  I drove it home a few days later.

     The sun roof has been opened 3 or 4 times in the 11 months we've had the car.  In the event that it ever leaks it will be removed, and the hole filled in.  The same goes for the rear deck spoiler.
