New to me chinese buggy identifying

[Raptorblitz]

Hi all, where do I begin. Just picked up according to the registration a Roketa GK13. At least that is what the local sheriff wrote it up as. I cannot for the life of me identify the make/model or engine to begin to find parts or repair manuals. Everything I see online is totally opposite of what I am finding. I have only found 2 numbers on this whole thing. The VIN which is only 15 digits has been impossible to track and one set of numbers on the motor case.
