I finally had the chance to flip through the service booklet that came with the 911. Now, the bulk of the records came in the form of invoices from specialist shops in North Carolina and Georgia, and those were certainly compelling reasons in my decision to buy the car.
That said, the tried-and-true method of tracking a car's history - the maintenance booklet - can be just as valuable. In the case of this car, the stampings were limited but meaningful. The early part of the car's history showed a few dealer stops in Wisconsin after being sold new by a fairly prominent dealer in a wealthy Chicago suburb. After it arrives in North Carolina, however, it makes two stops at Road Scholars.
Road Scholars is one of the foremost Porsche restoration shops in the country, if not the world. Between their personal collection of significant air-cooled Porches that routinely win at major Concours like Amelia Island and Pebble Beach and being hired to take on the restoration of historical and culturally significant cars, Road Scholars has an iron-clad reputation in the Porsche community.
This car already had a strong portfolio of proactive maintenance, but seeing Road Scholars in the maintenance book suggests a prior owner was only keeping the 911 serviced by the best of the best. I hope to get in touch with Road Scholars soon to see if they're willing to share whatever invoices they have on file for this car.
