That does sound frustrating! It's unusual that Admiral won't allow you to SORN your Boxster without canceling your insurance. Typically, insurers should offer a SORN insurance option for vehicles that won't be used on the road. It might be worth double-checking with Admiral to see if there's been a misunderstanding or if there's a specific policy restriction. If they still insist on canceling your insurance, you might consider looking into other insurers who offer such insurance cover for a smoother process.

Also, you could explore options to minimize the impact of canceling your insurance, such as checking if you can suspend your policy temporarily instead of canceling it outright.
