Ant heads to Scotland for a 1964 Mark 1 Cortina, but back at the workshop, he discovers an ominous knocking sound coming from the engine.

Ant falls for a 1989 Lotus Esprit but it's a gamble after losing £10k on his last Lotus restoration. His dad isn't happy when he finds out the car doesn't run. Plus, a bodged sunroof causes Ant a major headache. Structural cracks appear in the farmhouse.
