Trent wants to buy a new Porsche from the showroom floor. He wants a model with larger spoilers and side stripes, but he doesn't tell the saleswoman about these preferences. The model identified in the sales contract he signs doesn't have these features, although he believed it did. His unilateral mistake will:

Not relieve him of his obligation to purchase the car

Relieve him of his obligation to purchase the car

Might allow him to sue the dealership for the cost of the spoiler and stripes

Allow him to rescind the contract and recover costs and fees
