Watch Porsche's financing.. In the past couple years its gone down to 1.9% at the end of the model year, and stayed that way into the first couple months of the new model year (as it applies to buying a previous year car).
I'm sure there are a lot of guys that are smarter than I am about this, but I've found that the best time to buy is after the new model year cars are released. Buying a previous year car can save you thousands, however you'll be stuck picking from your dealer's stock, or working through their locator system to find a car that matches what you're looking for. The longer you wait the fewer cars you'll have to choose from.
Then there's the matter of first year depreciation, which is significant. Buying a previous year Porsche in the new model year will immediately impact its value when compared to a current model year car.
You're damned if you do, and damned if you don't..
