THE third annual Horsepower in the High Country show 'n shine, complete with kids’ activities, live music and food and beverage, revved up what’s believed to be another record number of cars and spectators this year.

The event, run by the Delatite Drivers Car Club in partnership with Mansfield Shire Council, and sponsored by Community Bank Mansfield and District, is a family friendly, community day out that also raises funds for Mansfield Autism Statewide Services.

Kerri Grant, school principal at Mansfield Autism, was thrilled with the turnout on the day and the strong support from the local community for the show.

"The support is phenomenal," Ms Grant said.

"It's extraordinary how the community gets behind Mansfield Autism.

"This event is really important in terms of fundraising for the resources that will help us implement best practice teaching in classrooms that are purposeful and meet the needs of our kids."

Dorothy Sutton of Euroa entered her hot pink 1932 Ford Coupe for the first time this year, in large part because autism services are a cause close to her heart.

As well as having grandchildren who are on the autism spectrum, Dorothy, owner of Yahoo Driving School in Benalla, takes great delight in helping autistic people, who've been told they'll never drive, to show the naysayers how mistaken they are.

"I teach a lot of autistic kids because I understand they may need to do things a bit differently, they'll need a break," Ms Sutton said.

"I get the kids on the road and some of them still ring me up and tell me how they're doing."

Mansfield Autism will use the funds raised from this years' show 'n shine to purchase furniture needed to fit out new classrooms and golf carts to assist those with mobility restrictions to get around the new 100 acre therapeutic care farm.

Funds are still being tallied but it is expected that fundraising will deliver over $20,000 to the farm's coffers.

Simone Reeves Chief Executive of Mansfield Autism thanked everyone who made the day a success.

“We just finished running a family camp at the Farm and I arrived to see the show in full swing, with smiles everywhere," she said.

"I’d like to thank everyone who entered, attended, donated, volunteered, sponsored and bought a raffle ticket, with special thanks to Cameron McGann of Delatite Drivers Car Club, Mansfield Shire Council and Community Bank Mansfield and District."
