The result is:
* Immediate engine shutdown: The car will lose power and come to a stop.
* Potential for serious internal engine damage: The pistons can collide with the open valves, bending or breaking them. This can also damage the cylinder head, pistons, and connecting rods. The repair cost for this type of damage can be very high, potentially exceeding the value of the car.
* No drivability: You won't be able to restart the engine until the timing belt and any associated damage are repaired.
In short: A broken timing belt in this car is a catastrophic event that requires significant and expensive repairs. It's crucial to maintain the timing belt according to the manufacturer's recommended schedule (typically around 60,000-100,000 miles, depending on driving conditions) to prevent this from happening.
