I bought a used car from a small dealership, they sold me the car without a dash harness, all the wiring that is supposed to be connected to the computer in my car is not there, so I can't do smog check. The mechanic could not check why the check engine light was on because the computer in my car was not communicating with the tool. Sold me the car with airbags not working. Lied about having it all checked out. And I still haven't received my title, registration, and plates to my car.
