Last weekend, only a couple of soccer goals rested on the bright green grass that surrounds The Gregory School campus.

This Saturday, more than 400 classic cars — this year’s featured model is a 1926 Bentley race car — and future classics, foreign and specialty cars will be displayed on that field from 10 a.m. to 4 p.m. Harley-Davidson will have a big display, as well.

During the past decade, the Rotary Club of Tucson has raised more than $1 million for local charities through its annual Tucson Classics Car Show. Last year more than 20,000 people attended, and organizers expect the same this year.

The $5 ticket for admission makes the event affordable for families — and offers the opportunity to win one of five significant prizes, the first of which is the choice of a 2008 C-6 Corvette convertible or $15,000 cash.

There also will be a children’s tent with activities, crafts and book giveaways, a food court, and booths with car accessories.

The club hopes to beat last year’s record proceeds of $209,000 to share among five local nonprofits: Make Way for Books, Joint Technical Education District of Pima County, Gap Ministries, CareGiver Training Institute of Tucson and the YWCA Women’s Impact Fund.

Make Way for Books, which is on a mission to give all children a chance to read and succeed by working with children from birth to age 5 and their families, will receive 40 percent of the proceeds.

In addition to raising funds, organizers hope to promote awareness about organizations such as Pima JTED, which offers advanced career and technical education programs across 13 member school districts in Pima County.
