Air An Rathad S07E04 - Episode 4

Murray gets behind the wheel of the all new Citroen Cactus this week. He's never been a huge fan of the Citroen brand, so will the Cactus change his mind? He takes it for a spin across the Pentlands and over to Edinburgh to find out. Linda is in Nottinghamshire test driving the world's smallest production car - the Peel P50. It's so small it makes a Smart car look big! A Ford Focus ST is Petrolhead Mairi Ross' car of choice. An old Volvo certainly isn't Donnie's favourite vehicle in Wacky Races, despite this he's currently in the lead. Murray and Linda are determined to catch him up - will they overtake him in this week's challenge?
