Description

1967 Porsche 911 Delivered new on April 12, 1967 to Owen O’Meara of Denver, Colorado, this short-wheelbase 911 Coupe has led an interesting life. After being sold to an enthusiast in Coronado, California, the car was repainted from its original Polo Red to an unintended darker Cranberry. In 2001 it was acquired by its third owner, a noted Bay-area auto journalist and SCCA racer, as a retirement project.

He stripped the interior and underside, made some minor rust repairs, and transformed the 911 into a vintage racer with a roll-bar, racing seat and harness, plastic door windows, fire system, and a fuel cell, adding silver stripes and rocker trim. In 2005 the 911 was sold to Steve Kupperman of Sacramento. The original engine was tired, so it was fully overhauled by a local dependent Porsche shop, which built the motor to 911 S-specification.

It tested out at a very strong 208 wheel horsepower on a chassis dyno. The suspension was properly sorted, and Mr. Kupperman would enter his car in numerous west coast vintage events, including two PCA Rennsport Reunions at Laguna Seca.

The car was sold to me about seven years ago; it has been driven infrequently since but not raced. This car, with all original and undamaged panels, has always been registered for street use. The car received major attention a year ago, with a full brake overhaul including caliper restoration, new rotors and pads.

There was also a valve adjustment, carburetor rebuild, new fuel lines, a new fuel tank, new shocks, and fresh fluids. The new tires are reported to have virtually no miles on them. Fuchs deep sixes all around.

The interior retains the factory S gauges, including the clock. Sparco drivers seat and the original passenger seat. Original wooden porsche shift know, documented in the COA. Really cool 60's Indianapolis 3 spoke steering wheel. fire supression system ect...

HMSA logbooks accompany the car, along with its original bill of sale, factory manuals, a dyno sheet. Also extra parts.

Classic Porsche 911 Buyer's Guide

The Porsche 911 has been in continuous production since 1964 — sixty years across eight platform generations — but the air-cooled era (1965-1998) defines the classic 911 market. From the long-hood early cars (1965-1973) through the impact-bumper G-body (1974-1989) and the 964 (1989-1994) and 993 (1995-1998) generations, each platform has its own engineering character, its own pitfalls, and its own collector trajectory. The Porsche marque is exacting in its documentation requirements, and buyers entering this market should understand exactly what separates a documented original car from a clone, a re-skin, or an outright fraud.

What to Check Before Buying

✓

Order Porsche Certificate of Authenticity ($254) — Available from Porsche Cars North America via chassis number. Confirms original engine, gearbox, color, options, delivery.

✓

Verify engine number stamping against COA — Stamped on flat pad on engine case (passenger side, near fan housing). Mismatch = 15-50% value reduction.

✓

Verify gearbox number against COA — Stamped on gearbox case. Original gearbox preferred; replacement gearboxes acceptable but reduce value.

✓

Inspect kidney bowls (pre-1976 cars) — Visible from inside footwells with carpet lifted. Critical structural rust point on non-galvanized bodies.

✓

Inspect longitudinal sills under doors — From underneath car with strong flashlight. Perforation = $8,000-$25,000 structural repair.

✓

Check battery box and front trunk floor — Battery acid leaks plus rust = perforation. Front trunk floor commonly rotten on neglected cars.

✓

Compression and leakdown test by specialist — Should read 145-175 PSI with <10% leakdown. SC and Carrera 3.2 head-stud failures are known issues.

✓

Inspect heat exchangers from underneath — Long-hood and G-body cars use exhaust heat exchangers for cabin heat. Rusted units = $3,000-$6,000 per side.

✓

Verify chassis number on body and dashboard — Multiple stamping locations should agree in style and patina. Mismatched = re-shell or body swap.

✓

Test all electrical and CIS fuel injection — Mechanical CIS (1973+) works well when serviced but fails expensively. Verify pressure regulator and warm-up regulator.

Common Issues

Air-cooled 911 rust is the structural killer for cars from any climate where road salt is used. The kidney bowls (the curved structural elements behind the front wheels), the longitudinal sills under the doors, the front trunk floor, the battery box, the suspension pan ahead of the front wheels, and the rear suspension mounting points are all critical structural rust zones. Long-hood cars (1965-1973) are particularly vulnerable because Porsche did not begin galvanizing the 911 body until 1976. Mechanically, the air-cooled flat-six is exceptionally durable when serviced correctly but unforgiving when neglected. Top-end rebuilds are required at 100,000-150,000 mile intervals due to head-stud failure (a known weakness on 1978-1983 3.0L SC and 3.2L Carrera engines), valve seat recession, and worn timing chain tensioners. The 1965-1973 Mezger-era engines are the most robust but also the rarest. Heat exchanger rust on long-hood cars is universal — a properly restored heat exchanger system is $3,000-$6,000 per side. Electrical issues vary by era. Pre-1972 cars used Bosch fuel injection (mechanical) on the 911S and 911E variants; 1973 brought the introduction of CIS (continuous injection system) which works well when serviced but fails expensively. Original wiring harnesses on long-hood cars are 50+ years old and prone to chafing in the engine bay where heat and vibration converge.

What to Look For

The Porsche Certificate of Authenticity ($254 from Porsche Cars North America) is the gold-standard documentation for any classic 911. The certificate confirms the original equipment of the car: engine number, gearbox number, color, interior, options, and delivery destination. For any 911 priced over $60,000, the certificate is mandatory. Engine and gearbox numbers are the second-tier verification. The engine number is stamped on a flat pad on the engine case (passenger side, near the fan housing). The gearbox number is stamped on the gearbox case. Cross-reference both against the certificate. Mismatched engine and gearbox numbers (versus the certificate) reduce value by 15-30% on driver-quality cars and by 30-50% on premium cars. Structural rust inspection is the first non-negotiable for any pre-1976 911. Lift the carpet at the driver and passenger footwells and look at the kidney bowls (visible from inside the car, behind the foot pedals). Inspect the longitudinal sills under the doors with a strong flashlight from underneath the car. Look at the battery box (front trunk, driver side on left-hand-drive cars). Look at the suspension pan ahead of the front wheels. Perforation in any of these areas is structural and expensive to repair — $8,000-$25,000 minimum for proper professional work. Car matching numbers (the chassis number stamped on the body in multiple locations) is the third-tier verification. The chassis number appears on the dashboard plate (visible through the windshield), on the front trunk hinge area, and stamped into the body in the front and rear suspension mounting areas. Mismatched stamping styles or different patina between locations indicates a re-shell, a body swap, or a fabricated car.

Price Guide

Long-hood 911s (1965-1973) are the blue-chip end of the market. Driver-quality 1969-1973 911T (the base model) cars run $65,000-$110,000. Documented 911S (the high-performance variant) cars run $140,000-$280,000. The 1973 Carrera RS 2.7 is the holy grail — $700,000-$1.5M+ for documented Touring (M472) cars and $1.2M-$3M+ for Lightweight (M471) cars. G-body 911s (1974-1989) are the bargain entry into air-cooled ownership. Driver-quality 1978-1983 911 SC (3.0L) cars run $45,000-$75,000. 1984-1989 Carrera 3.2 cars run $55,000-$95,000. Documented Turbo (930) cars from this era run $80,000-$180,000 depending on year and condition. The 1989 Speedster and 1989 Carrera Speedster are special cases — $120,000-$220,000 for documented examples. 964 generation (1989-1994) was the bridge between the air-cooled classic era and the modern 993. Driver-quality 964 Carrera 2/4 cars run $45,000-$80,000. 964 Turbo: $140,000-$280,000. 964 RS America: $95,000-$180,000. Project cars (running but rough) start around $25,000 for G-body cars and $50,000-$80,000 for long-hood cars. Stripped roller candidates can be had for $15,000-$35,000, but rust restoration on a long-hood 911 typically runs $50,000-$120,000 in body and structural repair alone. Buy finished cars from competent specialists — restoration economics rarely work on 911s.

Did You Know?

The 911 was originally going to be called the 901, but Peugeot held the trademark on three-digit model designations with a zero in the middle (Peugeot 304, 504, etc.) and threatened legal action. Porsche changed the name to 911 in October 1964, just before public launch — only 82 of the original 901 cars had been built and badged before the name change. Surviving 901-badged cars are now among the most valuable production 911s, with documented examples trading for over $1 million. The 1973 Carrera RS 2.7 was originally homologated for FIA Group 4 racing and required Porsche to build 500 road-going examples to qualify. The car was so popular that Porsche eventually built 1,580 — exceeding the homologation requirement by more than three times. The RS Lightweight (M471) variant weighed 200 kg less than a standard 911S thanks to thin-gauge sheet metal, fiberglass bumpers, and stripped interior. The air-cooled flat-six produced its final road-going version in the 1998 993 — and the engine architecture traces directly back to the 1948 Volkswagen Beetle flat-four via Ferdinand Porsche's design philosophy. The 1998 993 represented the end of fifty years of horizontally-opposed air-cooled engineering at Porsche.
