  • ✓Do not buy an M5 on a tight budget: tyres, brakes, clutches, and suspension parts are all expensive
  • ✓Check that oil services were frequent and specialist-led rather than stretched to dashboard intervals
  • ✓Listen for top-end noise, VANOS rattle, rod-bearing chatter, or turbo heat-related issues
  • ✓Test every electronic comfort feature because weak batteries and module faults cause chaos on older M5s
