A mechanic spends eight years building a motorcycle by hand in her garage. She decides to sell the motorcycle. She signs a contract and accepts payment from a purchaser. When the purchaser arrives to collect the motorcycle, the mechanic refuses to give him the keys and instead tries to return the payment. The purchaser wants the unique item, not the cash.

What remedy should the purchaser seek in court?

Specific performance, ordering the mechanic to transfer the motorcycle to the purchaser.

Enough damages to buy a different motorcycle in the same colour, with the same size engine.

A freezing order, preventing the mechanic from using her bank account as punishment for violating a contract

An injunction, preventing the mechanic from riding the motorcycle.
