You all are reading WAY too much into this about the VIN and data tags.
Even the most crooked who is going to try and pull some kind of fraud is going to do so with NUMBERS MATCHING! Is this so difficult to understand? Why would somebody knowingly try to engineer a fraudulent car and sale of car, and NOT MAKE the numbers match the paperwork? They would NOT. They would put some effort into making everything match. If you are trying to be fraudulent you don't let on at the beginning that things are not right. If that would be the case it would be far more cost effective to part the car out rather than sell it whole.
As for data plates, I've seen people with collections of them. Where do you think these come from? When our Pagodas were, not all that long ago, just older cars that didn't get $200,000 restorations, lots of little details were overlooked. Fender notches for one; how many cars that were worked on the 1970s, and 1980s and even later, never had these put back because they didn't know? How many had data plates removed and never replaced? I'll tell you one prime example: mine. Yes, the first body work on mine (since removed and re-done) was done by a "slap and dash" taxi garage in NYC. No data plate on the body either.
Some years back, with the assistance of someone here (before the Daimler lawyers shut them down) I had a body data plate properly made. I never had one before. I can tell you with 100% certainty that my "fake" data plate is far more original in appearance than the one you can buy from the classic center, either in Germany or the USA. Yes, the fake much better than a replacement. Not as good as the original of course but that was probably laying on the floor of a taxi garage and swept into the trash decades ago.
None of this has anything to do with being able to accept a car or walk away. The original poster didn't answer several important questions, instead, he's focused on posting lots of photos of the car and the paperwork. These questions are: how does the car run? Is it already in Thailand?
