Blurring the already subtle line between Porsches of new and those not-so-new, Porsche has declared that, starting this month, all certified used Porsche cars (and presumably that thing they call the Cayenne too) sold in the United States and Canada will be covered by a 50,000-mile/2-year warranty. That's almost as good as the 50,000-mile/4-year warranty you get on a brand-new Porsche. Of course, owners are still responsible for anything that's supposed to wear down, like tires, brakes, clutches, wipers blades, and the false impression that a Porsche will solve your mid-life crisis. Considering that it's already hard enough to see the year-to-year differences on a Porsche, this actually seems like a great alternative to buying new. Full details in the press release after the jump.

August 11, 2008 - Porsche has announced a significant upgrade to its Certified Pre-Owned (CPO) program that will now include an enhanced warranty for all CPO cars sold in the United States and Canada.

Since August 1, customers who purchase a Certified Pre-Owned Porsche will receive a company backed 2-year or 50,000m / 80,000km (whichever comes first) limited warranty that mirrors the new car limited warranty coverage. Additionally, for customers who buy cars with a balance of the New Car Limited Warranty Coverage, this remaining balance will be added to the new Certified Pre-owned Limited Warranty coverage.

Customers will only be responsible for normal wear and tear components such as brake pads, wiper blades and regularly scheduled maintenance. Twenty-four hour roadside assistance is also included in the pre-owned package.

"This upgrade to the CPO program will add even more value - and peace of mind - for these important customers, many of whom are just entering the brand; obviously, we want to create a very positive Porsche experience with these new customers,'" said Kevin Harvey, Porsche Cars North America's Manager, Pre-owned Operations. "Our goal is to make the pre-owned experience just as satisfying as the new car one."

Harvey said the CPO program at Porsche, which is now five years old, is growing in success each year, and this year he expects record results. North American Porsche dealers sold a total of 6,985 units in calendar year 2007. Sales are on pace for over 7,500 units in calendar year 2008. In the last five years, Porsche Dealer pre-owned sales penetration has grown from 16 percent of the total Porsche Pre-owned market to 33 percent. This is largely due to the on top sales volume the Certified Pre-owned Program has created for the dealer network.

Only the best used Porsches are selected as Certified Pre-Owned Porsches. Every certified used car undergoes a rigorous 111-point inspection and a detailed reconditioning process by Porsche -trained technicians whose goal is to bring the car back to new as close as possible.
