Bonhams’ Zoute Sale runs today, Sunday, October 11, from 13:00 to 17:00 local time, which is 7 a.m. Eastern at the start, in a marquee on the beach beside the Grand Casino in Knokke-Heist, according to Autonext’s weekend programme. The headline lots are the Keller Collection’s no-reserve Lamborghinis. The more interesting lot for collectors is the 1965 AC Cobra 289 that Bonhams offers separately at €700,000 to €900,000, because the pre-sale copy calls it “original, authentic and unmolested” while also disclosing that it has been converted to left-hand drive and repainted. The question this lot poses is what “original” means once a car has a history.
What is known about the 1965 AC Cobra 289
The facts below come from pre-sale reports by Magneto and Motor Sports NewsWire. We have not seen the Bonhams catalog entry, and neither report publishes the chassis or engine numbers.
- Model and rarity: one of 45 COB-numbered leaf-spring cars built in right-hand drive for the British market, per Magneto. Motor Sports NewsWire words it as one of 45 original AC Cobra 289s, so the exact framing of the count differs between reports.
- Original specification: sold new by AC Cars in Vineyard Green over Beige.
- Later changes: converted to left-hand drive and refinished in red when exported to California, which is its current presentation.
- Originality claims: it is said to retain its original chassis, body and engine, with the engine described as never modified.
- History: documented ownership from 1965 to the present, and it is said to have been driven coast to coast in America at least twice in period.
- Registries: listed in both the ACOC and SAA Cobra registries.
- Reserve: the Keller Collection cars are offered without reserve. Bonhams’ announcement presents the Cobra alongside that collection rather than within it, and the coverage we reviewed does not state a reserve for the Cobra.
Estimate and comparable sales
The estimate of €700,000 to €900,000 sits against a Shelby 289 market that Classic.com benchmarks at $991,897. Its recent results show how wide the range runs:
- August 15, 2026, Mecum Monterey: 1963 Cobra 289, CSX2105, $1,072,500.
- September 24, 2026, Bring a Trailer: 1964 Cobra 289, $791,000.
- January 23, 2026, RM Sotheby’s Phoenix: 1964 Cobra 289, $1,017,000.
- January 29, 2026, Gooding Christie’s Paris: 1964 Cobra 289, CSX2276, €792,500.
- January 28, 2026, RM Sotheby’s Paris: 1964 Cobra 289, CSX2255, €623,750.
The estimate midpoint of €800,000 lands almost exactly on the Gooding Paris result. Classic.com also lists a highest unsold bid of $1.2 million in January. Two cautions apply. These comparables are mostly Shelby American CSX cars, while this is an AC-numbered COB car, and Classic.com shows no AC COB sales, so any discount for the AC-numbered type cannot be measured from that data. And the page notes that some prices are hidden behind a paywall, so the list may be incomplete.
The key factor: what the conversion means
This section is interpretation. The bidding will probably turn less on whether the car is genuine than on how buyers read its changes. “Original” and “converted and repainted” are not contradictory if the changes are part of a documented life: a car driven across America in period, converted and refinished when it moved to California, still carrying its chassis, body and engine. In that reading the conversion is history, and the history is the appeal. If the conversion and repaint are recent, or undocumented, the same facts read as alteration, and buyers would price the car against fully original or correctly restored examples.
The coverage does not say when the car was converted or refinished, and that single missing date probably moves the price more than any other detail. A Cobra that can show its original right-hand-drive Vineyard Green spec, and a credible account of what became of it, is a different asset from one that cannot.
What bidders should ask before the hammer falls
- When, by whom and how the left-hand-drive conversion was done, and whether the original right-hand-drive components survive.
- Whether the red paint is period or recent, and whether any trace of Vineyard Green remains.
- The chassis and engine numbers against AC and registry records, since the reports do not publish them.
- The paper trail from 1965: sale documents, export and import records, and ownership letters behind the claim of a fully known history.
- What the registry listings in the ACOC and SAA registries actually record about the car’s originality.
- The reserve status, since a no-reserve car and a reserved one behave differently on the day.
For another lot in the same sale, see our earlier report on the no-reserve Miura P400 S, and for the same “what counts as original” question on a different marque, see our look at the 12,000-mile Mercedes 280SL Pagoda with a repaint and our guide to the Ferrari 308 GTB Vetroresina. The Cobra’s place among the great American-engined cars is in our ranking of the most expensive classic cars ever sold at auction. Results were not available when this was written, and we do not describe the outcome here.
Where’s your line: is a Cobra still “original” if the left-hand-drive conversion and repaint happened in period, or only if the paperwork proves when?
