Four celebrity pairs, 12 days, and over 3000kms of south-east Asia: it all adds up to an extraordinary rally, and one of the toughest classic (read: falling apart) car rides in the world. There’ll be loads of fun, plenty of laughs and breath-taking scenery, but they’ll also face the busy rush hour of northern Thailand's biggest city, Chiang Mai, the frustrations of obscure maps, and the phenomenally steep Chae Son Hills ... and that’s just in the first episode!
