Top Gear Technology Centre Caravan Airship review

You can buy a basic caravan for about £3.48, and the gasbag and burners shouldn’t be too much more. Then there’s hangar rental, pitch fees, a Caravan Club membership, plus the cost of nibbles and a large fruit bowl to hold everyone’s car keys at the party.

You will also need a runabout for when you land, but because it doesn’t need to tow a caravan any more, it can be something exciting. Such as a Lamborghini Gallardo.
