Inventor John Ward has been invited to take his pint-sized fire engine to CarFest, the event founded by Radio 2 DJ Chris Evans.
John converted the Reliant Robin himself and launched it on the country fair and show circuit in 2013.
But CarFest will be his biggest bash so far as his fire engine, named Freddie, takes pride of place in the emergency vehicle section of CarFest South over the August Bank Holiday.
John, from Moulton Seas End, said: “I think they are going from the ridiculous to the sublime and it doesn’t take a lot of thinking about which bit I fit into.”
John has appeared on TV all around the world with some of his madcap inventions, which include a bra warmer, a church font and the light at the end of the tunnel.
An American company wants to film him for a TV channel in the days leading up to CarFest.
“It’s cutting it a bit fine really, but I would like to go because it’s not every day you get an invite to such bashes as this.”
John is particularly pleased to be involved in CarFest because it raises millions of pounds for BBC Children In Need with £6.7m raised so far and £2.5m expected to be raised this year.
The festival is a mixture of vehicles, music and fun.
Music acts confirmed for CarFest South so far include Will Young, James Morrison, Jamie Lawson and Squeeze.
John was also invited to CarFest North, but couldn’t make the date.
His pint-sized fire engine is complete with a ladder, eight jets and a small hose.
The engine carries 50 litres of water and John can turn it into a water feature at the flick of a switch.
The fire engine is part of John’s “Little Berning Fire Brigade”, so named because it tackles little fires. Freddie has earned his place in CarFest with the launch of a new section for converted emergency vehicles.
