Live Fast, Die Hard

Team Cougar Bait is going to try to make the Sunday race. But rather than swap engines, they are going to swap cars. They are in the process of removing the roof so they can cut out the roll cage. They have access to a well-worn Saab 9-3 and have gone to fetch it. They intend to have the important pieces in the other chassis by Sunday's 8am race start.

Why replace the car instead of just the engine? The team was recently offered a car that had been involved in a deer accident. That car has a 4-cyl engine, whereas the engine in this car was a V6. Completely different systems.
