Thank you for the opportunity to help you with your question!
The statement seems ambiguous and does not make sense in terms of business since the amount will be enough to purchase a new car and even sell the old one to obtain economic advantage rather than using excess amount of money for the repairs.
Please let me know if you need any clarification. I'm always happy to answer your questions.
Spending $6000 on the car which has depreciated and has lost its value is not conserving and using the required amount that is enough for new car. Microeconomics requires that we spend the least possible rather than being extravagant.
