If I understand this correctly, you found two numbers on the car--one in the trunk and the other on the door pillar--that don't match. The title papers indicate a vin WPOAB9013ES121918, and in the car, one of the numbers is 911 7 202058. If this is correct, here's my guess.

You have a car made up of two cars--a 77 911 and an 84. The PO chose to title it with the 84 vin. At this point, there may not be anything to be concerned about if neither vin shows up as a stolen vehicle. That's a pandora's box you may not want to open.
