Look at it this way. The snake is gone, and probably took the varmint with it. Also, that passageway is certainly not blocked. This is why you should always check a car before entering. At least with a Fiero, there is no back seat for bad guys to hide in. If they want to hide in the trunk, well, that problem would solve itself, but they'd need to be removed before they started to smell and leak.
Yeah, a raccoon got into my sister's new Volvo SUV, so I'm not sure what'd be better.
