I've just insured my 'new' 1967 Carawagon for £75 for the year
That's fully comp and includes the 200TDi engine, legal cover, European breakdown recovery (to any destination), green card, 3 drivers including Patrick at 25 years young, and agreed value of £8000.
Ok, mileage is limited to 3000 miles, but that can be increased for "just a few pounds" when needed, and there's a stipulation that a fire extinguisher must be fitted (because of the 'furnishings'!).
RH Specialist Insurance is worth a call when your renewal is due
Cheers,
Robin.
