Drove a 76 4/4 for a decade ( not every day!) however sold it last year to buy a new 4/4 -got £1500 less back in a part exchange than I originally paid for it. Not bad depreciation for 10 years driving.
Only major thing I changed - was to fit a fan to help cooling when in traffic.
Whatever Morgan you drive - you drive that Morgan with its various little eccentricities - which include brakes, steering, suspension etc, etc,!
