price guide for e bay please
 

I have just brought a L reg single turbo legacy in running order but not keeping it for 3rd car so decided to strip and sell parts. What i am after is price guides for all parts. It has full leather interior including door cards too. Was owned by police force so unsure yet if they have done any mods to it.
Any help would be welcome

any ideas for prices ? full leather interior is now for sale to offers.
