Location. Pictures. Maintenance records. Those would be the best starting point. Also keep in mind what would make your wallet happy. There are High, Fair, and Quick Sale prices. NADA and KBB are total BS for these cars. It is quite rare that people get or pay those prices for a 107 these days.
300SL Euro is a special car being a "Gen2" that should have the same updates as the 560sl. They are not very common in North America. I've seen them sell in very wide price ranges.
Condition will be everything.
