I could run it at work, but considering the implications of how tough the California DMV is, and what I already stated (VIN tampering) the LEIN check is a moot point.
Even if LEIN shows either and both VIN's are clear, this does not preclude the fact there is VIN tampering. Knowingly posessing a car with a tampered VIN is a felony in most states.
As I mentioned before, as well, many others...simply put...
Run.
