All my Morgans are insured with Hagerty Insurance the 4 wheeled Mogs for over 25 years. They took on my 2013 M3W with no questions as a motorcycle having an agreed value of $55,000, so far they have renewed every year!!! They even paid out for a new engine on the M3W 5 years ago that saved me $10,000 without raising the premium. If you go with mainstream insurance make sure you read all the small print on all the pages, there have been some unsavory instances with Morgan owners who thought they were covered.
Does insurance normally cover an engine?
