yeh for $15 grand I could buy a nice running W140 S600, and a parts car to go with it...It may pull some codes, but how many? Of course, for that much money, it ought to pull them all. Not very cost effective if you want your own solution though.
I thought snap on charged extra for various car types. They used to have keys of sorts that were basically dongles to give access to optional models and years. Don't know if modern snap on systems are like that or not.
they want that much for their scanner.
