SPECIALIST sports car maker Caterham is celebrating 40 years of building and developing the iconic Seven model with a free limited edition pack.

The pack is available to the buyers of the first 40 Seven orders taken from today (May 9) and can be applied to any car in the Seven line-up.

Caterham Cars has been building the Seven since 1973, when original owner Graham Nearn acquired the rights to the model from Lotus chief Colin Chapman.

And while the brand has continually developed the famous sports car, it has never deviated from Chapman's original philosophy of ‘adding lightness' and placing the driving experience at the heart of the engineering process.

Available to buyers from the UK or any of Caterham's export markets at no extra cost, the pack has been designed to evoke the nostalgia of the early Sevens and includes optional equipment which would typically cost thousands of pounds.

The ‘40 Years of Caterham' pack includes the likes of grey painted chassis replicating the original Lotus Seven colour, ruby red ‘40YOC' paint with bonnet stripes, hand-tailored leather seats with grey piping and a grey leather dashboard.

You also get a bespoke tunnel top with grey handbrake and gearstick gaiters, a unique numbered  dash plaque, new 15-inch silver alloy wheels with Caterham embossing and Avon ZV3 tyres plus ‘40YOC' wheel centres and ignition key.

Caterham's current UK range of Sevens stretches from the Roadsport 125 at £19,995 to the range-topping Superlight R500 priced at £42,495.

Meanwhile,  Caterham has just introduced its most powerful variant yet - the Seven 485 - across mainland Europe.
