Morgan Plus 4 / Plus 8 / Roadster (Classic) Problems by Year

The classic Morgan range represents the quintessential British sports car, instantly recognizable by its sweeping wings, louvered bonnet, and traditional ash-wood frame mounted on a steel chassis. Built by hand in Malvern, these cars evolved slowly over decades, using a variety of bought-in engines from Ford and Rover (notably the Rover V8 in the Plus 8). In the UK, they are deeply cherished by purists who value craftsmanship, heritage, and a visceral, unassisted driving experience over modern dynamics. Reliability of the engines is generally solid, but the chassis and wooden frame require constant vigilance against rot. It is the ultimate weekend cruiser for traditionalists who view driving as an occasion.

Buying Tips for the 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.
