Concours in the Hills, scheduled for Saturday, Feb. 10, is growing in size and diversity of engine power.

Scuderia Southwest is bringing high-performance, exotic, collector and classic cars to Fountain Park from 10 a.m. to 3 p.m. The rain date is Feb. 17.

A Vietnam-era Cobra Gunship helicopter that flew in last year will return. An estimated 30 Cobra sports cars will be parked around the vehicle.

Organizer Peter Volyn said a Viper helicopter, the current version of the Cobra, will fly in from the U.S. Marine Corps base in San Diego. Vipers will encircle it.

A third helicopter, a 1969 Hughes OH-6A Cayuse, will be trailered to the park.

Scheduled to open the show featuring more than 600 cars will be two-time Indy 500 driver Arie Luyendyk; Indy 500 champion driver Paul Tracy; Lyn St. James, one of a handful of women who have raced at the Indy 500; Bob Bondurant, founder of Bondurant School of High Performance Driving, and Harley Cluxton, owner of the Mirage Racing Team.

A Marine Corps Color Guard also will participate in the opening ceremonies.

A special feature will be an 1897 Bugatti and a 1913 Bugatti on both sides of a contemporary Bugatti Veyron. Two rare, expensive LaFerraris, a hardtop and Spider (convertible) will be displayed. Some rare Jaguars valued at millions of dollars each also will be there.

Awards will be given to Best Import, Best Domestic and Best of Show. The Ferrari Club of America Desert Region will conduct its own judging and other clubs may do so also.

Proceeds from exhibitors’ entry fees will go to Phoenix Children’s Hospital. The exhibitor vehicle entry fee is a minimum $60 donation. Admission to spectators is free.

Last year 647 vehicles and 71 sponsors/exhibitors participated, said Volny. Attendance was estimated at more than 15,000. The event raised in excess of $90,000 for the Boys & Girls Club, that year’s charity partner.
