Jaguar E-Type (Shadow69/Bigstock.com)

Jaguar doesn't like to leave a job unfinished. Or so it seems, as the company confirms it will be building six Lightweight E-types of a production run of 18 that was never fully completed in 1963.

Only 12 of the special racing E-types were finished, of which 11 are still in existence.

The six 'new' E-types will be built precisely to original specifications, although like the first 12, they will have certain unique elements – specified by those who order them.

And Jaguar is going to be very picky about who is able to make this grand purchase. Aside from having over a million pounds in ready cash, each owner must intend to use and enjoy the car – not leave them in storage or in a museum.

Along with the original aluminium body spec, the car will feature the same 3.8-litre six cylinder engine, as well as boasting vehicle identification numbers of Sixties design.

The cars will also be FIA approved to race at classic events, even though they are technically brand new.

While the price tag of £1m may seem high, Tony Schulp, the man who will sell the racer, pointed out that Lightweight E-types from the original batch now fetch between £3-4m.

Future owners of the 'new' E-type need not fear that they'll be calling their annual breakdown cover provider too often, since the vehicle – in common with most Sixties cars – is so simple inside there isn't much to go wrong. Indeed, the Lightweight version has even less equipment than a regular E-type, as the name suggests.
