Essentially, I want the ubiquitous "car mechanic goes under the car on the little wheeled board thingy and does . . . something" scene. But I have no clue what the mechanic would be doing since I know nothing of cars, or what the little wheeled board thingy is called. Could someone please tell me (on both counts)?
If it matters, the mechanic in question doesn't have a full shop set up. All his gear is makeshift, found, etc, and he's working in an old warehouse, so he doesn't have the huge shiny lift to raise a car up completely like I've seen in a few of the mechanic pictures.
