The “Greatest Car Show on Grass” celebrates its 11th year of Concours in the Hills.

The annual car show is planned for Saturday, Feb. 15, from 10 a.m. to 3 p.m. at Fountain Park.

This free, family-friendly event benefits Phoenix Children’s Hope Fund, a critical source of funding for the hospital’s areas of greatest need, according to a press release.

These funds support pioneering research, state-of-the-art technology, recruitment of leading physicians and the implementation of programs designed to create a more comfortable hospital environment for children.

Concours in the Hills features awe-inspiring vehicles including contemporary and classic race cars, exotic foreign and domestic high-performance cars, muscle cars, sports cars, hot rods, military vehicles, helicopters and motorcycles, all while providing vital support to children at Phoenix Children’s.

Event admission and parking are free to spectators but donations are welcome.
