Magnetic trackers are increasingly being used by car thieves to steal classic vehicles. These small, discreet devices are often attached to the chassis or hidden within the body of the car, making them hard to detect. Once in place, the tracker transmits the car's location in real-time to the criminal, allowing the thieves to track its movements. 

Moreover, the thieves will use this tracking data to profile the owner; to see how the owner uses his classic. Once a vulnerability is identified, the thieves will strike. 

For example, you meet your classic mates at a coffee shop meet-up advertised on social media; the thief is an also a member of this social media feed. Thieves arrive and unbeknown to you place the magnetic tracker as you sip away on a cup of robusta blend. Then each time thereafter you visit a classic event, he can identify when you are away from your vehicle and strike.

Owners should invest in advanced more advanced security systems and regularly inspect their cars for any signs of tampering to prevent such thefts.
