TL;DR
A one-of-a-kind 1953 Aston Martin DB1 Spider, created by Paul Jackman using a modified BMW chassis and original Aston Martin components, has been auctioned. The car’s history includes racing at Le Mans and museum display, making it a significant collector’s item.
A rare 1953 Aston Martin 2.0-Litre DB1 Spider, built by Aston Martin’s then-head of development Paul Jackman, was sold at auction, emphasizing its rarity and historic importance for collectors and enthusiasts.
This bespoke sports special was constructed in the early 1950s on a modified BMW 320 chassis, featuring aluminum roadster bodywork by Green & May, and powered by a 2.0-liter inline-four engine originally used in the Aston Martin DB1 that competed at Le Mans in 1949. The car was registered in 1953 as an Aston Martin Sigma and remained with Jackman for four years before changing hands and eventually moving to the United States.
The vehicle was cosmetically refurbished in Germany in 1991 and spent several years on display in a museum. In 2011, an English owner commissioned engine and transmission overhauls, and the car was later sold in 2022. It has since been shown at prominent concours events such as the Audrain Newport and Amelia Island Concours d’Elegance. Finished in green with white roundels, the car features distinctive design elements including an oval grille, exposed headlights, and rounded fenders. Its braking system includes aluminum drums sourced from an Aston Martin DB1, and it rides on painted wire wheels wrapped in Vredestein Sprint Classic tires.
Why It Matters
This vehicle’s significance lies in its unique construction, blending original Aston Martin racing heritage with bespoke engineering by Paul Jackman. Its racing history, including participation at Le Mans, and its rarity as a one-off special make it a highly valuable collector’s piece. The car exemplifies post-war British sports car innovation and bespoke craftsmanship, appealing to both historic racing enthusiasts and collectors of rare automobiles.

Background
After World War II, Aston Martin developed a 2.0-liter sports car prototype based on the Atom chassis, which claimed an overall win at the 1948 24 Hours of Spa. This design evolved into the DB1, with a limited number of chassis produced. One of these was equipped with a ‘Spa replica’ engine and raced at Le Mans, finishing fourth in its class. The engine was later repurposed into the special built by Paul Jackman, who welded a steel-tube support frame onto a shortened BMW 320 chassis, then clad it with aluminum bodywork. The car was registered in 1953 and remained with Jackman until the late 1950s, after which it changed ownership multiple times, eventually arriving in the U.S. Its restoration history includes a cosmetic refurbishment in Germany and engine work in England, with recent appearances at major concours events.
