Ne'er-do-wells who find themselves getting pinched tomorrow could be forgiven for admiring their plush new surrounds.

The vans, based on the Holden Colorado, will be phased in across Victoria over the next two years, replacing the existing fleet that were first seen eight years ago.

The new vans have more storage, an additional camera and airconditioning in the custody compartment, and an improved digital siren system that is louder and can be operated via the vehicle's horn.
