James went first, and though he wound up looking "like a spaniel that's crashed into the back of a hen" according to Jeremy, he only had his glove box lid and radio panel dislodged while having 4 grams of egg left in his colander, giving him £20. Each would earn £10 for each gram of egg left in the colander at the end but lose £10 for each trim piece that fell off. The presenters were shocked to find that the fourth test, designed to test ride comfort, called for them to drive on the rough road at 30 miles per hour (new cars are typically tested on that road at 25 miles per hour) - with a colander of eggs attached to the roof lining of each car above the driver's head. Richard then tried it, but the Dolly's handbrake failed to hold it, sending James and Jeremy into fits of laughter at the sight of it rolling back down the hill, whereupon it hit the grade sign. He claimed he had done it - a claim that neither Richard nor James contested. James went first and succeeded, while Jeremy raised a cloud of smoke from wheel spin while trying to get to the stopping point.
The test that followed called for each presenter to drive up a 1-in-3 (33.3% grade) hill, stop at a specified stopping point, put on the handbrake and get out, with £100 awarded for a success. James missed a turn and then got lost on the track. Jeremy came closest at only a second behind in the Rover, while Richard ended up five seconds slower. The benchmark was 1:11, and despite having more powerful cars, none of the presenters was able to beat it. The power test consisted of timed laps on the handling circuit, with the mark to beat set by the Stig in a Datsun 120Y. Instructed to travel 40 miles from their starting point, the presenters mistakenly arrive at each of the three previous British Leyland factories, only to find each of them with a different lease of life, before ending up at the MIRA test track, described by James as an "automotive torture chamber." The journey served as a reliability test, but no presenter earned money because none of them had managed to complete the journey without having reliability problems. The presenters began the challenge at Warwick Services on the M40, where the trio revealed their choices: Segments British Leyland Challenge Main article: British Leyland Challenge Introduction & Choices
