Buying Tips for the 1999–2000 MG Rover Rover 75 / MG ZT

  • ✓Check the plenum chamber (below the wipers) for standing water; blocked drains will flood the engine ECU, destroying it.
  • ✓On 1.8-litre models, verify if the head gasket has been upgraded to a multi-layer steel (MLS) version.
  • ✓On KV6 models, listen for a rattle from the intake manifold, indicating failing VIS (Variable Intake System) motors.
  • ✓On diesels, check for smooth power delivery; failing low-pressure fuel pumps or MAF sensors are common.
  • ✓Inspect the rear tubular subframe carefully; they are highly prone to severe structural rust and are expensive to replace.
