Slick-backed 1950s-style rockers from Sheffield (Rockin' Rabble) and a crew of slick estate agents from Surrey (Hot Property)built fully functioning fire engines. Each vehicle would be tested for a race to resuce a stranded doll on second floor of a wooden house, a race to douse the burning barbecue grill, then the race to douse the flame on the wooden house.
Rockin' Rabble built on top of a pickup truck with a giant tank and a paddle pump. Hot Property built from a van with a smaller tank and pump.
In challenge day, Hot Property won the rescue race, Rockin' Rabble led on barbecue grill event. In third race, Rockin' Rabble's vehicle's pump broke, so the teammates had to use water bucket. Hot Property eventually ran out of water, but not before dousing most of the flame. Hot Property won the third round and the match.
