Jason runs a second-hand car sales business. He buys cars from auction and from private buyers and sells them on. He's not a mechanic himself but uses a local firm to check the cars and carry out any required work. Gary buys a vehicle from Jason following a test drive. The vehicle originally had seat heating, but Jason tells him this is no longer working though everything else on the vehicle should be fine.

a) After two weeks there is a problem with the clutch and Gary asks Jason to repair it along with the heated seats.

b) After seven months there is a problem with the rear axle and Gary thinks he may return the car and ask for his money back.

c) Gary suffers a minor injury taking the car back to Jason because of an accident caused by a fault on the vehicle. Apparently, this model of vehicle was recalled by the manufacturer for repair of this fault a year ago, but Gary's vehicle has not had the fault repaired.

d) After eight months, the police inform Gary that the car was stolen, and its details changed so that Gary was not aware of the vehicle's history.
