The 1983 Daimler Double-Six would use Jaguar’s 5.3 litre V12 first seen in the 1971 Jaguar E-Type. By 1975 the E-Type’s four carburetors had been left on the shelf and the engine updated with electronic ignition and fuel injection which increased both reliability, economy and power. With fuel injection, the 5.3 litre jumped from around 270bhp to a respectable 292bhp and 298 N·m of torque, and when mated to a robust General Motors TH400 3-speed automatic transmission, enabled the ‘Six to pull from 20mph all the way to 140mph in third gear!

Fuel economy is as expected from a 5.3 litre V12. While some engines carry the ‘HE’ (High Efficiency) moniker, MPG returns are not going to be a topic of conversation you’ll want to chime into, but offer a perfect opportunity to nip to the bar for a vodka and tonic. After all, there’s a reason the Double-Six has double the fuel tanks!

The Double-Six was an immensely expensive vehicle in 1985 with forecourt prices around £43,000, approximately £134,000 in today’s money. The choice carriage of the Royal Family and self-made businessmen who wanted power, elegance and above all else, comfort. The Double-Six doubled down on creature comforts, with individual rear seats, an abundance of fine wood trim, cruise control, air conditioning and electric front seats and windows.    

‘Grace, space and pace’ are in the very fabric of this Daimler’s DNA. Ride comfort remains unrivalled by all but the likes of Rolls-Royce, such is the quality of the suspension that the Double-Six can remain level whilst cornering at 60mph. 

Supplied new in 1985 by Hares Group Ltd in Rustington (Sussex), this ‘Six was maintained by Hares for much of its life until 2010 where it made the long drive north to Scotland and later Huddersfield. 

Presented in a deep Bordeaux Red and still on the original Daimler 15” alloy wheels. The interior is truly a testament to its low mileage and previous owners’ care, with almost no evidence of wear to the driver’s seat or evidence of passengers in the rear seats.
