Buying Tips for 1950–2019 Morgan Plus 4 / Plus 8 / Roadster (Classic)

  • ✓Inspect the ash-wood frame (visible under the rear wheel arches and door sills) for any signs of rot or woodworm.
  • ✓Check the steel chassis cross-members for severe corrosion, particularly on cars driven in wet weather.
  • ✓Look for "scuttle shake" during the test drive, which can indicate worn suspension components or loose body mounts.
  • ✓Verify the condition of the "sliding pillar" front suspension; it requires regular greasing to function correctly.
  • ✓Check the radiator for leaks or overheating; Morgan radiators are often bespoke and expensive to replace.
  • ✓Ensure the weather gear (hood and sidescreens) fits securely, though expect some water ingress in heavy rain.
