Good evening, I been trying to search for this movie for about a decade. It was somethingrecorded on to a VHS; the tape no longer exists (prob pre 2002). The film starts with a struggling, but talented mechanic who is discovered by a fancy-pants man who invites him to a party. At the party the mechanic sees his car collection, and finds a demon/alien baby in a jar with curtains in the room shrouding the jar credenza. Mechanic makes a deal to be famous. Later in the movie there is a scene where they found a rare car where a limited amount were made; they used another years make to sell for lots of money. The mechanic uses magnesium or something to change the VIN. Any help is appreciated. Thank you for reading!
