Rainman,
mine is with state farm (2000 Zetec). It was originally insured through Parish Heacock, and I had thought only specialist insurers would touch these cars. However, I moved all my other car insurance over to SF a couple of years ago, and my agent wanted to bid on the Caterham, so I said as long as they could match the PH policy - including full replacement value - they could have the business. After a bit of back and forth, they gave me a policy with the same benefits/deductions but at around $250 less per year :thumbs:
My mileage limit is 3000 pa, but I'm sure you could go for more. I would not mention that you are using it for commuting - that could be a deal beaker. It helped a lot that the agent seemed to want to get the business IMHO.
Good luck.
