I was wondering if anyone could tell me what the black / blue book price ranges would be for a 1976 530i (not California emissions). It is in very good condition with 93,000 miles (149,000 kms) on it. Silver with blue leather interior. I am interested in buyingvthis car however I think the guy selling it is dreaming considering what he is asking for. I would appreciate any input or anyone who can direct me to a website that can provide black / blue book values for this car. Thanks e12 ers.
