MG ZS (Classic)
The MG ZS was the pick of MG Rover's 2001 range for drivers, turning the comfortable Rover 45 into a sharp-handling saloon and hatchback thanks to its Honda-derived double-wishbone front suspension and multi-link rear. The 2.5-litre KV6 ZS 180 is the enthusiast's choice, with 175PS and one of the best front-wheel-drive chassis of its era, while the 1.6 and 1.8 K-Series cars are cheaper to run and insure. UK values are low, so buy the best body you can find: sills, rear arches and boot floors rust, and the V6's timing belt and VIS inlet motors are expensive if neglected. K-Series head gasket failure is the other big risk on four-cylinder cars. A well-sorted ZS is still a bargain driver's car, but a neglected one can cost more than it is worth.
