No, not really, even assuming it is a true VIN of this car. Ask for a lot of pictures, including pictures of underneath areas, VIN number, number stamped on the hood, paint code plate and VIN plate (if too new, I would be suspicious).
But I would not buy based on pictures only.
If you are looking for a Pagoda, Become a Full Member here, look through the buyer's guide, go there with someone who knows fair deal about cars and check it out. Check if the VIN is original and not tampered with, check for rust if there are reasons to believe the car is genuine.
I quick rough check may be if you get to see the data card (have you asked if they have datacard?) and paint number plate is to check if options and colors are matching (unless, of course, altered).
I would not buy based on pictures.
Make appointment, ask for the car to be cold when you arrive to see it (to check for oil leaks where she stands and for engine work from the moment it is cold) and take it from there.
I am a bit suspicious as they do not want to share the documents with you. I do not get why would they not do it.
