I came across these pictures of a 360 Modena with what has been described as a 'Factory Sunroof'. I have never seen one with this option before.
I always thought it was a shame the 360 and 430 didn't come in GTS/targa versions. The GTS was the perfect solution for me as I don't really like cars with a fixed roof and the lines of the cabriolet hood on the spider versions spoils the look of the car. The GTS offered the best of both worlds. I don't really think the argument that GTS's are not water tight hold any weight, as most Ferrari's never see the rain and most aren't left parked outside for great periods of time. My old 328 GTS wasn't watertight but it wasn't an issue for me. I've owned many convertible cars, most of which leaked like a sieve in the rain - especially my MG's. But it goes with the territory, I always expect a drop top to leak when I buy one.Apparently Ferrari gave up on the GTS idea with the 355's and decided not to compromise structural integrity coming up with the removable roof portion concept.
Andrew,I just picked up my 2000 360 modena and mine has this option. I personally love it. You get a wobble at high speeds if your side windows are up and it is open but if it is a nice sunny day like we have been having in MN this summer then it is great!
