The show also features Hammond's prized 1963 Opel Kadett car named "Oliver", which he acquired for the Top Gear: Botswana Special.
Loyal, yet incompetent servant-like men which Hammond refers to as "Lab Rats" also appear in every episode.
According to the introductory credits, the secret lab is supposed to be located beneath Mapledurham Watermill in Oxfordshire.
In episode 7, the bias against caravans, which is often brought up in Top Gear and in Brainiac, continues, with one being wrecked by a fiery catapult.
Despite having been regressed to a youngster, Mini-Miss is shown to not suffer fools gladly, particularly Hammond, whom she always chides for some misdemeanor or other reasons; such as not paying attention, for example – she goes to give the teams advice prior to the start of the round.
