Andy is driving a 20-year-old boat that he borrowed from a friend. While he's on the water, the steering system fails and the boat crashes. Subsequent investigation shows that the steering system failed as a result of corrosion. Andy sues the boat manufacturer for negligence.

How strong is his negligence case against the product manufacturer?

• Weak, unless he can show that the corrosion was the result of a design defect rather than normal wear and tear on a 20-year-old boat.
• Strong, because proximate cause between the corroded steering system and the crash is easy to establish.
• Weak, because he does not have privity of contract, since he was borrowing his friend's boat.
• Strong, because there is no evidence that Andy's own actions contributed to the damages.
