1. the cost of the truck ($54,000)
2. their own legal fees to defend themselves in the lawsuit
3. triple damages (for fraud)
4. the plaintiff's legal fees
5. punitive damages
This can turn into a $500,000 loss very easily. And if they lose a fraud case, it's not covered by insurance, either.
Those awards are not going to happen. It's a simple breach of contract case. The plaintiff gets the amount of damages suffered as a result of the breach (here, the truck or its value) and the defendant pays the award and its own attorney fees.
