Common Problems with the
1971 Lotus Elan (M100)

The 1971 Lotus Elan (M100) has an excellent reliability record with no widely reported common faults for this model year period.

Buying Tips for 1971 Lotus Elan (M100)

  • Inspect the rear suspension wishbones thoroughly from above and below; corrosion attacks the upper surface where water and road grime collect unseen.
  • Test the 5-speed manual gearshift; worn shift cable ball-joints or stretched linkage cables cause vague engagement and difficulty selecting 2nd or Reverse.
  • Operate the retractable pop-up headlamps; verify both motor actuators raise and lower smoothly without sticking or electrical delay.
  • Examine the front undertray, intercooler, and low-slung oil cooler for scrape damage or cracked composite fixings caused by speed bumps.
  • Check footwells and behind the seats for dampness, confirming the soft-top seals and A-pillar weather-stripping remain pliable and watertight.
