I have just purchased a ex mod / sas ? range rover to use as parts
it still has a commision plate with its working no .
all i want is the engine and box is there any value to the rest or should it be weighted in ?.

That depends on its condition and are you prepared to break it or sell as a rolling chassis/body.

Breaking it will take time/storage space and probably return more cash than selling as a rolling shell, where scraping it will return much less.

Posted pictures of general condition might get some interest/reaction from interested parties.
