Gillian and Martin Ross and their five children were initially overjoyed with the car they bought from the dealer. But after just two days, their new motor suddenly cut out, causing the family to narrowly avoid a collision. After consulting a local mechanic, they were told that their new car was a worn-out mess. The brake pads were shot, the air bag broken and the fuel injection system out of order. The car should never have passed the MOT. It turns out that Gillian and Martin Ross were not alone. Single mum Stephanie Robertson worked part-time at a local supermarket and had spent the past year saving up for a car to allow her to commute to college and take her young daughter to school. She wanted a reliable and safe vehicle – but what she got from the dealer was unreliable and dangerous. Melinda is determined to do all she can to try and help these families out, but this time she is miles out of her comfort zone. Meanwhile, Dom's investigation kicks into gear as he uncovers a trail of other unhappy car owners – and discovers that this is one cowboy who might be about to get his just deserts.
