The final year of the long-hood 911S Coupe finished in its original color combination of Gemini Blue Metallic over Black leatherette with houndstooth inserts, this 1973 Porsche 911S represents one of the most desirable evolutions of the early 911. As the last year of the long-hood body style, the 1973 911S combined the strongest 2.4-liter S-specification engine with the upgraded 5-speed manual transmission (Type 915), delivering the high-revving character, mechanical precision, and improved drivability that continue to make these cars among the most sought-after of the early 911s.

Delivered on July 19, 1973, by Rothausen Porsche Audi of Bellingham, Washington, to its first owner, Clarence Kesselring of Burlington, Washington, accompanied by the original maintenance and warranty booklet. Factory options include U.S. equipment, Blaupunkt AM/FM radio, electric sunroof, tinted glass all around, and Michelin tires. The 911S has remained under the same family's care for the past eight years and benefits from significant documented service and refurbishment during that period.

The paintwork presents beautifully and is complemented by excellent gaps and panel fit. The interior features Black leatherette upholstery with sport-style seats and houndstooth inserts, one of the most attractive interior combinations. On April 15, 2019, the front and rear seats were upholstered by Auto Interiors of Mission Viejo, California. The VDM instruments were removed and restored by Gail's Speedometer, further enhancing the cockpit's clarity and finish. The interior is complete with an original Blaupunkt AM/FM radio, factory instrumentation, leather-wrapped steering wheel with butterfly horn ring, and the purposeful layout that defines the early 911 driving experience.

Extensive service records document mechanical and cosmetic attention. In May 2017, Carrera Car Shop of Huntington Station, New York, performed a major engine rebuild, including splitting the case, rebuilding the cylinder heads with new valve guides, line-boring the case for the crankshaft, machine work, and installation of new pistons, piston rings, connecting rod bearings, crankshaft bearings, and head studs. The same invoice also notes a comprehensive list of detail and correctness items addressed throughout the 911, including instrumentation restoration, trim and seals, lighting, engine compartment details, undercarriage, wheel refinishing, handbrake repair, radio and antenna installation, engine tin refinishing, and numerous period-correct components.

Additional parts invoices from 2017 through 2020 further support the scope of the work. Items sourced included a new Dansk muffler, hot air hoses, a driver-side flag mirror, correct decals, sun visors, quarter-window latches, hood mounting plates, seal and trim pieces, a 911S engine emblem, rear center panel seal, door panel welting, chassis and door jamb plate rivets, rear engine grille, and numerous small hardware and finishing components.

Subsequent service by Aase Motors in Fullerton, California, documents continued mechanical servicing. In April 2018, the stacks were balanced and the timing and mixture adjusted. In April 2019, the 911S received a fuel pressure check, CD unit replacement, tachometer adjustment, points replacement, timing reset, and idle and mixture adjustment. In early 2020, Aase Motors performed further service including valve adjustment, oil and filter service, fuel sender replacement, front hood shock replacement, rear sway bar bushing lubrication, relay replacement, injection adjustment, and additional mixture and idle adjustment.

Mechanically powered by its 2.4-liter flat-six engine (Type 911/53) producing 190 horsepower, paired with the original 5-speed manual transmission (Type 915), and four-wheel disc brakes. The 911S delivers the sharp throttle response, high-revving performance, and unmistakable character that define the top-tier early 911S. Complete with the Porsche Certificate of Authenticity, owner's manual, original maintenance and warranty booklet, Blaupunkt radio manual, Porsche technical specification booklet, two keys, dealer supplements, and supporting service records. This 2.4-liter Gemini Blue Metallic 911S Coupe represents an excellent opportunity to acquire a highly desirable final-year long-hood S in an attractive factory color combination, desirable options, and extensive documentation.
