A Signal Red 1965 Porsche 356SC Coupe that has answered to a single owner since it was ordered new in 1964 is down to its final hours on Hagerty Marketplace, where bidding has climbed to $65,000 across 39 bids ahead of a Tuesday, August 18 close at 2:00 p.m. EDT. The car wears chassis 130951, carries a Porsche Cars North America Certificate of Authenticity, and has drawn more than 18,000 views and two dozen comments on the listing.

The Last and Best Version of Porsche’s First Car
By 1965, the 356 had been in production for seventeen years, and the C-series that closed it out was the most thoroughly developed car of the entire run. The 356C brought four-wheel disc brakes to the line for the first time, and Porsche fitted larger anti-roll bars and a steering damper to civilize the swing-axle rear end that had made earlier 356s such an acquired taste at the limit. Sitting at the top of the pushrod ladder was the SC engine: a 1,582cc air-cooled flat-four rated at 95 horsepower, the most Porsche ever extracted from the architecture that started the company before the 911 rewrote the formula entirely.
That is why SC coupes remain the 356 variant collectors chase hardest. The earlier cars carry more period romance — a 1954 Pre-A Speedster or a split-window early coupe will always turn more heads at a concours — but the SC is the one you can point at a mountain road without apologizing for the brakes. Motorious has tracked a steady run of these lately, from a preservation-grade 1960 356 B Super 90 to a restored 1958 Speedster with strong provenance.
Ordered in Bangkok, Delivered to Delaware
The provenance here is the headline. The original purchase agreement, included with the sale, is dated August 12, 1964 and was written in Bangkok, Thailand, where the buyer — a U.S. serviceman on deployment — placed the order through Tourists International Est. of Geneva, Switzerland. Porsche built the car on September 16, 1964 in Signal Red (paint code 6407) over black leather, and it was shipped to the Port of Wilmington, Delaware. It has lived in Delaware, New Jersey, Pennsylvania and Maryland ever since, always under a garage roof, and it is now offered by the family on the original owner’s behalf.
The paperwork backs the story up in a way that very few sixty-year-old Porsches can manage. Along with the Certificate of Authenticity and that original purchase agreement, the sale includes service records, the factory tool kit, a matching spare wheel, a spare Europa radio and a clean Maryland title in the current owner’s name. The COA confirms SC specification, the 741/2C four-speed transaxle, ventilated chrome steel wheels and an engine number that matches the chassis number.
It has not gone unnoticed in the comments. Broad Arrow senior car specialist Ramsey Potts, who disclosed that he has no connection to the car, the seller or the bidding, wrote in to praise the family for keeping the car alive for six decades and predicted it would be among the coolest 356s at any Porsche event it attends. The seller’s daughter has been fielding questions directly, noting the car has been a fixture in the family garage her entire life.
A Refurbishment Measured in Years, Not Weekends
The work was done in stages over more than a decade, with receipts. Fifty Plus Cars in Maryland rebuilt the engine in 2011–2012 using an NPR 1,750cc kit, machining the flywheel and rebuilding the generator, fuel pump, carburetor and distributor along the way, plus a new clutch disc, pressure plate and throw-out bearing. In 2015, Wills Werks of Fairfax, Virginia performed a complete transaxle rebuild, and the car received four rebuilt calipers in yellow zinc finish, Koni shocks, steel brake lines, a new master cylinder, tie rod ends and a fresh steering damper.
Vredestein Sprint Classic tires went on in 2018, the body was repainted in June 2024, and the most recent service came just last month: Erdle Automotive in Laytonsville, Maryland cleaned and adjusted the points, cleaned and regapped the plugs, drained and flushed the fuel system, and pulled the carburetors to clean every jet and reset the idle. The interior was reupholstered in black leather, the chrome and engine-bay hardware refinished, and new windshield and rear glass fitted.
The listing is candid about what is not perfect. The odometer reads 91,200 miles and is designated TMU. The factory radio does not work. The displacement is now 1,750cc rather than the original 1,582cc, a well-known and widely accepted 356 upgrade but a departure from stock all the same. And the seller amended the listing mid-auction to correct an earlier line about the nose panel — the front assembly was never replaced, only the right-hand headlight bucket — which is the kind of correction that tends to build confidence rather than erode it.
What the Hagerty Price Guide Says About 356SC Money
Hagerty Valuation Tools value a 1965 Porsche 356C 1600 SC coupe in #3 (Good) condition at $130,000, with the cabriolet version of the same car at $195,000 and trending up 11.4 percent. Hagerty’s data set counts 369 public auction sales of the 1965 356C 1600 SC over the past three years, with the most recent trading at $224,000 on August 15, 2026, and pegs the typical good-condition, average-spec example at roughly $142,500. The high-water mark over that three-year window is $762,500.
Set against those numbers, a $65,000 high bid with hours left on the clock looks like a lot of 356 for the money, even accounting for the increased displacement and the TMU odometer. Broadly, the collector market has been recalibrating — Hagerty’s own market rating recently fell to its lowest level in nearly 15 years, even as the company continues to see momentum in parts of the classic-car market. What has held up best through that reshuffling is exactly what this car has: documentation, continuous ownership and a story that cannot be manufactured.
Why This One Is Worth Watching
Plenty of 356SCs come to market. Very few arrive with the original purchase agreement, a Certificate of Authenticity, an engine number that matches the chassis, and a single family name attached to the title since the Johnson administration. Whoever wins this one becomes only the second owner in sixty-plus years, which is a rarer distinction than any options list.
