When your family fails its MOT, it's time to look UNDER THE BONNET...With a struggling second-hand car dealership in South London, Juliet and Andy Wyevale don't have it easy. And it's not just the business that needs a jump-start -- their relationship could do with an overhaul too. Andy's always too busy with work to help with the kids, and what's more, he's losing his hair and gaining a paunch. Although Juliet loves her husband dearly, she knows the passion leaked out of their marriage a while ago. So when Andy hires Steve, a gorgeous young mechanic with an appetite for fast motorbikes and older women, the sparks begin to fly. Will Juliet risk it all for a tumble on the tarmac? Or will she realise her family needs her now more than ever?
