For the third year running, the team of two will hit the bitumen for the four-day charity event from March 19 to 22 travelling in their 1969 Ford Fairlane.
Mr Gardiner said the car did not need a lot of preparation but given how old it was, he would give it a good service, complete detail and spend the weekend before polishing the chrome.
More than 90 participants and officials and a record 27 cars will take part in the cruise that starts in Bunbury and moves through Balingup, Pemberton, Walpole and Albany before finishing in Collie.
Mr Gardiner said the couple continued to sign up for the event because they loved Variety WA and being able to see their fundraising come to fruition.
‘Along the way, we go to special needs schools and hand over goods from iPads for special needs children to buses with special chairs,’ he said.
‘The best thing is seeing the smiles on the kids’ faces.’
To take part, participants must contribute a minimum $4000 donation or $3000 for new cars.
For the past two years, the Gardiners have held a fundraising dinner and show at Sandalford Winery.
This year they aim to be the top fundraisers, with the dinner already collecting $26,000.
