tdw28210 had a key suggestion for any online purchase:
A reverse image search.
Save this link:
https://www.google.com/imghp?sbi=1 Just copy the image location of any image and it will show you most anywhere that image can be found on the web even if it is resized.
Another reverse search is
https://www.tineye.com/. It works the same way.
I'm not sure why it didn't pop for
tdw28210 via Google as I show the car for sale right now in Cadillac Michigan.

Neither of those ads seems to list the VIN number which seems odd for a car sales website. I wonder what that car's VIN is...
