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.
