An incredibly rare Aston Martin that may have been used as an unmarked police car in the sixties has been found after half a century hidden in a garage.

The DB2-4, built in 1955, was discovered at a property in Gloucestershire and is believed to be worth £250,000 when fully restored.

The classic car, which became famous as the model driven by James Bond in Ian Fleming’s novels, was bought by a car enthusiast who intended to work on the engine when he retired.

Instead it was covered by a sheet and forgotten by its owner, who died before the Aston saw the light of day.

The car was finally discovered when the garage was cleared five years after the owner's death.

The coveted vehicle was perfectly preserved – coated in a thick layer of dust and with 60s newspapers still stashed in the boot.

Blue details on the car's spotlights suggest the Aston may have been used as an unmarked police car, but much of the vehicle's history remains a mystery.

Jonathan Wills from Cotswold Classic Cars said: “It is incredibly rare for such a valuable car to disappear for such a long time.

“As it was only driven for 12 years, it still has its original interior - and it really is a unique find.

“Now we’re putting the car on the market to be restored back to its former glory or to be kept as a time piece.

“Restoring the vehicle will cost between £60 and £130,000 depending on the level of restoration required by the potential purchaser.”

Cotswold Classic Cars specialises in Jaguars, Aston Martins, Maseratis and Lancias – ensuring the valuable vehicles remain in tip-top condition.

Classic car enthusiasts from Mauritius, Dubai, Singapore, Canada, Netherlands, as well as all over the UK, bring their cars to the Cotswolds to be restored by the team.

Director, Jonathan Wills, has been restoring classic cars for over 20-years, but admits the barn-find Aston Martin is something extra special.

“What marks this car as absolutely unique is it’s an Aston Martin DB2-4, which the build numbers were only in the few hundreds anyway,” said Jonathan.

“Most of them have either been scrapped and are no longer around. The few that are left are absolutely cherished and command considerable values.

“To actually have a blank canvas, a car carrying such history, such rarity, you’re not going to find this again.”

“This particular car is very hard to value because it is so unique in the fact that it was only on the road for a few years and has been stored ever since.”

If this vehicle is to undergo a full restoration the car will be broken down into all its component pieces and even the body taken off the chassis.

All the components are thoroughly cleaned and inspected and then rebuilt as to original specification. Jonathan then puts the options to the customer so they can either build the car to original specification, or modify it slightly to bring the driving dynamics up to 21st century standards.

The team can improve steering, suspension and brakes - making cars safer and faster on today's roads.
