PORS9 ... World's Largest Porsche Registry and Owner Network


What is PORS9 and the PORS9 Registry?

PORS9SM is common short hand for Porsche throughout the world and is an acronym for what we are Porsche Owner’s Registry SiteTM. ‘Porsche Nine’ is the worlds largest vehicle database and registry for Porsche millennial GT, Turbo and Limited Series 9** models originally sold in North America. The PORS9 registry was developed by Concours By Appointment, a bonded and licensed specialty brokerage.

How does it work?

Anyone can search our database using our database Search App. Once vehicles of interest are identified we can contact their owners to engage a purchase transaction. As a highly specialized broker we facilitate documentation exchange and price negotiation. Post sale we affirm vehicle and title transfer. We provide our services to buyers and sellers.

Here are the steps to working with PORS9 to acquire or market a vehicle:

  • Step 2: For buyers, identify vehicle purchase candidates using the Search App. Browse the vehicle profiles to drill down and narrow the focus. The Search App allows you to search the entire database in order to view the specifics of Porsche 9** vehicles meeting specific characteristics meeting your criteria such as year, color, build specs, options and much more. With search results in hand contact us to help you to further screen possible vehicle acquisitions.
  • Step 3: For sellers, contact us to discuss your vehicle and how we can market it for you using our unique marketing tool-kit and programs.
  • Step 4: We go to work behind the scenes to contact match buyers and sellers.
  • Step 5: Once a match is made we hands on manage the prepurchase process and price negotiation to reach a successful purchase.

What is the Search App and how do I use it?

The Search App is the window into our proprietary database. It is an intuitive step through search tool that uses a subset of parameters to identify actual production vehicles initially sold in North America. In real-time our sorts through our entire database of 20,000 Porsche VIN’s to generate a list of specific vehicles matching user defined parameters. Once satisfied with a selection of matches users can submit to receive detailed build summaries of the individual vehicle’s included in the search results.

What Experian Autocheck data do you share?

We have an agreement with Experian to share critical data on select vehicles. Experian data can only be viewed by those with Member status. Experian Autocheck print reports are also available through us.

How do I know what to search for?

The data sections of our website contain the world’s most comprehensive collection of Porsche vehicle information publicly available from a single source. There can be found, listed by model and year, standard and optional specifications and their descriptions, actual production interior and exterior colors, and full production summaries. We are proud to say that everyone from novice enthusiasts to subject matter experts use our data as educational and reference material. We are the open source for Porsche data.

Do you purchase vehicles?

Although we contractually function as a purchase intermediary we do not purchase vehicles for inventory. We operate as a match-maker only. We do not compete with our clients or dealers for vehicles and we never step in front of a transaction. We do not take title to vehicles.
What is ‘member status’ and how does my status affect my experience using PORS9?
Your status defines your relationship with CBA and your interface with the PORS9 registry.
Casual visitors are ‘Subscribers’. Visitors who register become ‘Members’ and can view various depths of data in the database not available to Subscribers.

Once you contact an owner what happens?

We verify certain minimum information regarding the vehicle, including current mileage and condition. We also determine if the owner is interested in entertaining an offer for their vehicle. If they are interested we will commit to a purchase negotiation process and if the buyer and seller come to mutually satisfactory terms then a purchase transaction is consummated.

Can I have a prepurchase inspection?

Yes. CBA can arrange for a pre-purchase inspection at the buyer’s expense. Inspection may be provided through our tech inspector partners or at a seller designated location agreeable to buyer. Generally most any requirement can be accommodated if agreeable to the seller.

Can I view the car personally?

Yes. Prior to closing CBA can arrange for the buyer to view the vehicle in person before final payment.
When does the seller get paid, how do I get the vehicle title and the vehicle?
We are responsible for obtaining all documentation from the seller. Purchase monies are not transferred to a seller until the buyer is satisfied with the vehicle’s condition and documentation. Upon proof of good funds to seller, we obtain the fully executed, free and clear, good title to the vehicle from the seller. Upon receipt of good title, purchase funds are transferred to the seller to close the transaction and the vehicle title is forwarded to the buyer. The buyer will then connect with the seller to arrange vehicle transport logistics.

What does the service cost?

There is no cost for our services unless a transaction closes. Our fixed commission structure is stated upfront and is the lowest in the business! Contact Us to discuss our commission program.

Why don’t you provide VIN information?

There are several reason we do not provide Vehicle Identification Numbers (VIN’s) first and foremost of which is protecting the privacy of owner identities and vehicle locations. Legal and commercial data services also place restrictions on the disclosure of VIN related information which in turn limits our ability to share this information until a purchase transaction closes. Seller’s also may require that their vehicle not be ‘shopped’ in the traditional sense. Since vehicles are not identified by VIN in the PORS9 system, even if a vehicle is widely offered to our client base, by design it cannot be ‘shopped’ (as that process is commonly understood) as it cannot be individually identified. Finally, VIN’s and associated information, including owner information, are the proprietary data of CBA and our stock in trade. Qualified buyers will always know the VIN and have access to VIN related documentation at the appropriate time prior to purchase.

Why are owner identities hidden?

We have a strong reputation for protecting owner privacy. Privacy is an important part of what owners require to maintain confidence that will not be inundated by unwanted solicitation from dealers, brokers and prospective buyers as a result of working with CBA. We are highly respected for using formulated policies and procedures designed to protect owners from unwanted solicitation and work to maintain 100% anonymity.
