However, stringent rules surrounding the bid mean she has to find a certain model to be absolutely sure the attempt is accepted by the governing body.
Despite months of planning and searching she has still not tracked down an original Mini Cooper made between 1961 and 1969 or a replica of the original made between 1996 and 2000.
She needs to fit 22 people into the retro car to claim the wacky title and has been given access to a new car so the attempt will go ahead regardless.
“Hopefully by following all the other guidelines we will still be able to get the record but Guinness haven’t been very forthcoming about that,” Fiona said.
“It’s a frustrating process dealing with them as they take a long time to reply to queries but we will go ahead as planned and hope for the best.
“But I’m still holding out hope that someone will be able to provide me with a proper model of car in the next week.
“I can pick it up and take it back and it is insured for the day. It doesn’t even have to work, as long as it has all the internal fittings like seats, steering wheel and gear stick.”
The record attempt is part of Fiona’s Inspire event — an afternoon of challenges to motivate and energise young people, arranged as part of her recently completed college course.
There are activities for anyone aged from five to 21 on the plaza at Perth Concert Hall, like song and story writing, rapping and clothing design.
The Inspire event takes place from 1-5pm, with the record attempt at around 3.50pm.
