Hi there, kind of depepends what you plan on doing. If you plan on driving 30 thousand kilometers per year, including rain and snow, then there is only one car: the 911. However, if you plan on driving only a few thousand miles in good weather, them it doesn't really matter. It's important to point out that all three cars, which you listed are very different automobiles. The Maserati is a Luxurious GT car, whereas the Ferrari has much more emphasis on handling/performance. The Porsche is of course a sports car as well, while offering an amount of luxury. If you want maximum head-turning effect, go for the Ferrari. If you want the best of all worlds while still having everyday and all weather drivability with good build quality, then go for the 996. While I am a big fan of the Maserati as well, I think think that it's only suitable for people placing a strong emphasis on elegance and exclusiveness. Depends on what you're looking for. Nonetheless, I envy you for being in a position that you can chose between the three.
