Derek discovers the holy grail of Austin Mini barn finds, a rare and valuable 1965 Cooper "S" 1275cc. The car has been hidden in a garage full of rubbish for 30 years and appears to be a worthless rusty wreck, but on auction day it generates a flood of interest and a bidding war among classic Mini enthusiasts. Meanwhile, faced with a deadline to get a late entry into the auction catalogue, Paul decides he'd like a Bentley Continental for himself and attempts to persuade his wife it would be perfect for the school run. And a fan of 1950's Americana faces a difficult choice as two Chevy Stepside pickup trucks go under the hammer.

A slice of Yorkshire classic car history rolls into the showroom. Derek dives into the archive of the lost Jowett marque as the Bradford built ‘52 Javelin finds an unexpected home. Paul and Dave uncover a Ford Escort that's been untouched for 30 years. The barn find sparks a bidding frenzy. Meanwhile, a teenage buyer takes a punt on a cheap MGB GT in poor condition. A Mathewson's customer reveals his elaborate man cave tucked away in his garage and office manager Sarah discovers that classic car and dog ownership don't always mix.
