Hi Mog1998,
Assuming you are in UK.
My experience is that insurers are unwilling to insure the Morgan Three Wheeler for anyone under 25. Old or New models. I am currently rebuilding a 1937 Morgan Three Wheeler owned by The Morgan Three Wheeler Club and the insurance specifically states that it is insured for any driver over the age of 25. Drivers under 25 excluded. that policy is with Morgan Insurance Co ( Headley Insurance) 01420 594242 Call them to check.
I do know that Peter James Insurance has been looking at providing insurance for our younger members but am not sure if he came up with a suitable policy. 0121 506 6040 Call them to check.
From the long time I have been involved with Morgan Three Wheelers I know that insurance for under 25's is a problem.
Good luck, Ian
