Meet Bob. Bob's car was destroyed by Alice, thus besides other potential consequences, rendering Alice civilly liable for the value of the car.
Suppose that the car was bought on a temporary, time-limited promotion by the company wherein they were being sold for an early bird 50% off RRP, which promotion is no longer available.
Or, suppose that Bob had bought it for £1000 in a once in a lifetime sweetheart deal from his father, when the lowest one can find such a model of car for in functional working condition on the market is £5000.
Never again could anyone conceivably find that type of car again and replace it for £1000.
However, Bob's purchase receipt for his car shows a purchase price of £1000.
What was Bob's civil loss that Alice may be civilly liable for?
England and Wales sought, answers of all jurisdictions welcome.
