Big Mark and Little Mark test-drive a British Military classic – a Landrover Defender 90. But the boys leave the owner more than a little frustrated off when they go off-piste with her precious car. Then, Vicki and Simon get the chance to buy a Victorian skeleton, will they snatch this body up for the right price or make a grave mistake? And a set of original Alice in Wonderland sketches make their way to the shop.
