I was expecting an Aygo or some other modern Toyota shite, but I shall let you off! An old dear local has a pretty much identical G reg one that looks rather tidy, I've not noticed if its auto or manual, but betting the former, I shall try and have a nose at some point.
Of course, your other alternative with the sunroof is disconnect the switch, however, myself, I'd rather have a nice working roof you can open up this nice weather, let a bit of sun in, even if I have to slap factor 50 on the old pate!
