According to the Association of Chief Police Officers Vehicle Crime Intelligence Service (AVCIS), and other vehicle authorities, the Ford Transit van was the most stolen van in 2009, 2010, and 2011.
However, Transit van insurance policyholders must now be wary of another crime which has been befalling some van owners in Hertfordshire and the West Midlands, amongst other places.
In Bishop's Stortford (Herts) and many different areas of Telford near Wolverhampton, thieves have been stealing catalytic converters from a range of different vehicles, including vans.
The catalytic converters from two Mercedes vans were taken by thieves in Bishop's Stortford who are thought to be selling them for the scrap metal value, and Transit van insurance policyholders' vehicles may also be at risk.
A detective chief inspector from Hertfordshire states, "Metal theft, in particular the theft of catalytic converters, is an issue across the country and, in Hertfordshire, is one we are working hard to tackle."
She adds that residents and business can help the police stop metal thieves by reporting suspicious behaviour, such as "people hanging around vehicles at unusual times", and by parking their vehicle in their driveway or garage if they have one.
People with business van insurance may want to take particular care of where they park their vehicle, since thieves may try to break in to steal tools from the rear of the van.
The best advice to avoid falling victim to vehicle crime is to park in a well-lit place, in a driveway or garage, and not to keep expensive work tools in the vehicle overnight.
