Three vehicles were broken into on the same night in Saffron Walden last Friday.
One car, a Ford Capri 2.8i, was torched – leaving little more than a rusty shell once the fire service had doused the flames.
On the same evening, the steering lock and dashboard were damaged on another car, while the handbrake of a campervan was released after criminals gained entry, leaving it to roll into a block of flats.
The news is the latest in a string of classic-car thefts, which are thought to be rising as new cars get harder to steal and the demand for parts rises.
Popular classics with thieves include Minis, Mk1 and Mk2 Ford Escorts, plus VW campervans.
Police are urging owners to fit tracker devices or, where possible, ensure their pride and joy is not visible from the road.
