Thieves have made off with this rare 1968 Triumph TR5 during a burglary at a house in Buxton.
The red convertible was parked at a house in Lascelles Road when the property was broken into overnight between May 12 and 13.
The burglars took the keys from inside the property and drove off in the Triumph.
Police believe the car was one of a short production run and was made between August 1967 and September 1968, making it quite rare.
They are hoping that will help them trace it and are asking people to be on the lookout for it.
