About the sunroof....... Of all the MGBs I have had, only one has been a GT. I had an opportunity to buy a sunroof like the one in this car. I put it in myself. Although it was not an original style. I absolutely loved it. You could pop it open, open the cowl vent and have fantastic flow through ventilation. It made the car nice and light inside, and with very little trouble, the whole panel could be lifted out. When I sold the car, it was the sunroof that made the deal. It is a "try it, you'll like it" situation.
