Porsche recently announced the launch of their car subscription program, one which should tame the most serious case of showroom indecision. The program lets prospective buyers trade in one model for another at will. It will be test marketed in Atlanta, and, if all goes well, more broadly offered next year.

The program—which Porsche is calling Passport—is offered in two different rate levels. At $2,000 per month, a Porsche aficionado has their choice of a Cayman S, a Cayenne SUV, a 718 Boxster, or a Macan S, and associated variations. That’s the Launch level, and, just to reiterate, you may present your Passport at any time during your travels for a four-wheeled switcheroo.

At the $3,000 per month Accelerate level, you may begin with the 911 Carrera, if you wish, before moving on to the not-so-utilitarian Macan GTS, the ecologically relevant Cayenne S hybrid, and the executive’s choice, the Panamera 4S. In all, 22 model variations are included here.

It’s all smartphone app-controlled, and sounds as simple as notification followed by drop-off and pick-up at the desired location…depending on the available stock pool of vehicles earmarked for the program, naturally. Insurance, taxes, and maintenance are all covered in the subscription rate fee.

As part of the program, Porsche will charge a $500 activation fee for entry into the program. Not bad, really, when one considers the consolations of needing a garage with a revolving door. Porsche’s leadership sees the benefits to the company as myriad, but most importantly this: the quick expansion of a loyal customer base which need never stray from the fold for the sake of novelty or altered consumer demands.

To top it off, unlimited mileage and unlimited flips; Porsche is making drivers an offer they can’t refuse.
