Why it matters
The Jet is a one-off steel-bodied coupe by Bertone on the last DB4GT chassis completed in period, 0201L. It was styled by the 22-year-old Giorgetto Giugiaro and is the only DB4GT with a steel body. Its Geneva debut in 1961 coincided with the Jaguar E-Type launch, which overshadowed it.

Every figure says what it counts.
| What is counted | Figure | Basis | Status |

| Total model productionthe single Jet, chassis 0201L, restored by Aston Martin Works Service and sold in 2013 | 12 | Surviving examples | Independently researched |
| Total model productionOne-off on the final DB4 GT chassis (DB4GT/0201/L); page lists "Numbers built: 1" | 11 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Aston Martin sent the last standard DB4GT chassis to Turin two months after the DB4GT Zagato was unveiled in late 1960. Bertone, working from a design by Giugiaro, finished the car in time for the 1961 Geneva Motor Show (17-27 March), painted light green with a grey interior. It was shown again at the Turin Motor Show late that year, by then painted blue.
After its show career the car spent time in Beirut and the United States before Aston Martin chairman Victor Gauntlett found it in the 1980s and had it shipped back to the factory. Works Service completed a total restoration at Newport Pagnell in 1988, and the Jet went on to win numerous concours awards. Bonhams sold it at the Works Service sale in May 2013.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
The Jet is chassis DB4GT/0201/L (written 0201L) with engine number 370/0201/GT, and is unique. Unlike the production DB4GT it has exposed headlights either side of a wide rectangular intake with a hexagonally patterned grille, chrome quarter bumpers above brake-cooling scoops, a larger oil-cooler inlet, and a bonnet power bulge with thin vertical vanes. Vents sit behind each front wheel, the pillars are slim with opening quarterlights, and the rear screen runs into a sloping tail. Only the sills and the front and rear aprons are aluminium; the rest of the body is steel. The dash is body-coloured with a black vinyl top.
