It was launched at the 1959 New York Motor Show, and its greatest success was in the American market. It had a fibreglass body, four wheel Girling disc brakes, and a 2.5 litre Hemi-head V8 designed by Edward Turner. Although really a two seater, the car had a small bench rear seat.
The original A-spec version could do 120 mph (193 km/h), but the chassis, a “14-gauge ladder frame with cruciform bracing” based on the Triumph TR-3, flexed so much that doors came open, marring its reputation.. Bumpers (fenders) were originally an optional extra.
Jaguar bought Daimler in 1960, and were immediately concerned about the chassis flex. They brought out the B-spec version with extra outriggers on the chassis and a strengthening hoop between the A posts. There were also other detail improvements, including an adjustable steering column.
There was a C-spec version introduced in 1963 with some additional luxuries as standard equipment.
2,645 were produced.
Jaguar built a prototype replacement (known as the SP252) with a neater body style but decided not to proceed with production.
Ogle Design produced a coupe version called the SX250, but this was not taken up by Daimler and the body design was later used for the Reliant Scimitar.
