Need a little help here I have a guy that wants me to make an offer on his G1 MIB Mega Zarak it's 100% complete no chrome wear but also no instructions or stickers though. Box is is in about C8.5 condition styrofoam is good too not discolored or torn up. Toy is solid nothing loose or broken. It's like it came right out of 1987 with a mild case of shelfware lol. What would be a good non-slap in the face offer?
