As usual - shop around - Headley (Morgan Insurance) gave me the best rates for the Morgan, but Classic Line were best for the XJS. Tried to get some sort of multi car discount from both if I covered both cars with the same insurer, but Headley quoted way more for the XJS and Classic Line quoted way more for the Morgan. Strange as I assume the driver risk is the same and the values were fairly similar, engine's are both 4 litre etc etc.
