You'll need to ring a few classic insurers - it is definitely possible to get these cars on a classic policy, but you need to find out which one works for you. As for getting an agreed value insurance, each insurer is a little different. Some insurers will charge for it, while others offer it as part of their policy. Normally, you'll need to send in five or six recent photos showing all angles of the car. If you've spent a lot on the car recently to increase its value, your insurer may wish to see proof of this. But you don't have to pay for an independent valuation - the insurers have their own team to verify a vehicle's value.
