When the new management took over Aston Martin in the early 1970s there was one hidden asset - a design for a long wheelbase four-door model to bear the Lagonda name. In fact this car was designed first and one of them was built for the personal use of Sir David Brown. The then current Aston Coupe, though widely acclaimed as a clean and well balanced modern design, was actually a shortened version of the sedan.

By late 1974 Aston Martin launched the Lagonda model, appropriately named the Aston Martin Lagonda. It had a wheelbase 30cm longer than the coupe - the extra space was used to provide comfortable rear seats with decent leg room. Upholstery was in English hide, while the front seats had reclining backrests and there was a passenger footrest.

The Lagonda had electric control for windows, door locks, boot lock and fuel filler. Equipment included a heated rear window, internally controlled door mirror, a fire extinguisher and a stereo radio/cassette player. There was air-conditioning with two four-speed blowers which could provide through flow or recirculation to heat or cool the interior as quickly as possible. Aluminium body panels were mounted on a steel frame fixed to the chassis platform, which was rust proof and undersealed.

The light alloy V8 engine of 5340cc, with four chain-driven overhead camshafts, four Weber twin choke carburettors, and transistorised ignition, drove through a five-speed gearbox with overdrive top or Torqueflite three-speed automatic. Steering was power assisted rack and pinion and suspension was the normal Aston Martin layout with wishbones and coil springs at the front, and a De Dion axle at the rear. The exhaust had twin-pipes and five silencers.

Gearbox ratios were the same as in the coupe and the axle ratio, at 3.54 to 1, was the lower of the two available on the coupe. With automatic transmission the ratio was 3.07 to 1. Brakes were Girling ventilated discs with separate circuits for front and rear and two vacuum servos.

The Lagonda's at launch price tag of UK£14,000 put it in the top bracket of exotica prices on the British market, including Rolls from UK£15,000 upwards from the Silver Shadow to the Phantom Six Park Ward at nearly UK£19,000, the Mercedes-Benz 600 at UK£18,000 to £25,500, the Ferrari Boxer at £16,400, (the 365 GT4 was approx £14,000), and the Countach at nearly £17,000, (The Espada was £13,400 in Britain). Next to Rolls it was the most expensive local car as the others were imports with duty bagged on.

The irony of the Lagonda was that, like so many models from its stable, it had been launched at a time when the winds of change blew a positive gale. But to swim against the tide was in the best Lagonda tradition. Most new models in Aston Martin Lagonda's previous history had been launched to stave off financial tempests. In 1975 the Aston Martin Lagonda group was swimming in a sea of red ink. It had appealed - without success - to the British government for massive assistance to keep the firm afloat. Little else was left, except to gamble on the magic of the Lagonda name to weather the storm.
