It's the last programme of the series, and Donnie is in love! He's fallen for an Italian beauty, but what is it? Linda is at Lochgelly following the junior stock car racing, where kids as young as 9 are giving it welly on the race track. Linda dons a helmet and finds out how fiercely competitive the kids are for herself. No friends on the track, as they say. Alasdair MacLeod tells us why he loves his Subaru Impreza, and it's the final challenge of Wacky Races. Can Donnie hold onto his lead? You'll have to watch to find out!
