Valuation Required For 1985 Corolla Gt Coupe 16v

[Albatross]

I have found an insurance company that recognises my 1985 Corolla GT Coupe as a classic/cherished car from the 1980s and is willing to insure it as such on a limited mileage classic car policy. They also aknowledge the present true value of the car - in the region of £8000-10000- rather than its value based on it being a 23 year old Corolla with 87K on the clock (a couplr hundred quid). The only problem is that they require verification of this valuation from the Toyota Owners' Club. Any ideas how I go about this? They also require proof of my membership of the Club as I get a discount for being a member. I have recently purchased Silver membership but have no offical proof of this; membership no etc, (perhaps this will arrive in the post shortly) Can someone please clarify the situation for me.
