About the Aston Martin International
Built during Aston Martin's formative years under the ownership of Augustus Cesare Bertelli, the International was designed as a road-going version of the company's racing cars. The model featured a 1.5-litre overhead cam four-cylinder engine producing around 56bhp, mounted in a lightweight chassis with half-elliptic leaf springs and cable-operated brakes. Most examples were fitted with two-seater open bodywork, though some saloon and coupé variants were produced by coachbuilders including Bertelli himself.
Only around 80 Internationals were built during the three-year production run, making them exceptionally rare today. The model achieved notable competition success, including class wins at Le Mans and the Tourist Trophy. Surviving examples are now treasured pieces of British automotive heritage, regularly appearing at historic racing events and concours gatherings.
What Affects the Price
Originality is paramount when valuing an International. Cars retaining their original engine, chassis and coachwork command significant premiums, with documented racing history adding further value. Matching numbers and continuous ownership records are highly desirable, as is evidence of period competition participation.
Condition varies enormously across the surviving population. Fully restored, concours-quality examples with professional rebuilds can exceed £100,000, whilst project cars requiring complete restoration may be available from £35,000. The quality and authenticity of any restoration work directly impacts value, with period-correct components and proper coachwork far more desirable than modified or incorrect specifications.
Rarity of body style also affects pricing. Standard two-seater sports models are most common, whilst saloons and coupés command premiums due to their scarcity. Cars with continuous UK history often sell for more than repatriated examples, and those eligible for historic racing or rallying events attract competitive bidding from enthusiasts.
Buying Tips
Documentation is critical when purchasing any International. Verify chassis and engine numbers against factory records held by the Aston Martin Heritage Trust. Request a full history file including old MOT certificates, registration documents and photographs showing the car's condition over time. Be particularly cautious of cars with gaps in their provenance or unexplained changes of identity.
Commission a pre-purchase inspection from a specialist familiar with pre-war Aston Martins. The ash frame beneath the aluminium body panels is prone to rot, whilst the engine's overhead camshaft design requires expert assessment. Brake and suspension components can be difficult to source, so check condition carefully. Original parts are scarce and expensive, making cars with non-standard modifications difficult and costly to return to correct specification.
Factor in running costs beyond the purchase price. Insurance for a vehicle of this value and rarity requires specialist historic car cover. Maintenance demands a skilled engineer experienced with vintage machinery, and parts fabrication may be necessary for unavailable components. Budget for secure, climate-controlled storage to protect your investment.
