The silver ZT-T 190 is virtually a standard showroom model with air conditioning and electric front windows, with livery fitted by decal specialists Halo Blue Light, of West Sussex and the police light roof bar and ancillaries by Woodway of Coventry.
The ZT-T 190 uses a 187bhp version of MG Rover's 2.5-litre K-series V6, and accelerates from 0-60mph in 8.2 seconds, with a top speed of 137mph.
It includes sports suspension, and the estate provides extra space for special equipment like traffic cones, lights, road signs, first aid kits, brooms and shovels.
Gavin Thompson, MG Rover's police sales manager, said: 'On the basis that you need one to catch one, the MG ZT-T is precisely the dual purpose vehicle that traffic police require.
'With its powerful quad-cam V6 engine and versatile luggage capacity, the ZT-T provides the necessary combination of a sports performance car and the functionality of an estate - ideal for police forces throughout the UK.'
