As far as what you like, you don't seem to mention anything specific to the essence of the car, which is that it's a purpose built convertible.

Why not consider an older 996 Carrera? It's essentially a two seater and although the upfront cost can be slightly higher (or lower depending on mileage) the maintenance costs are practically the same: high. And the costs of unexepected repairs are equally high since it's the price of parts and not so much much the labor that make owning the car pricey.
In other words if you're going to brave the Porsche waters and aren't really a roadster guy, then why consider it over a Carrera?
Some make the mistake of thinking that the Boxster will be more affordable way of getting into a Porsche than a 996/997 and base their decision to buy on that premise, but after a $5K repair bill for shocks, clutch/ims and water pump, they soon discover that's not really the case.
