John Cena's passion for classic muscle cars is no secret to the WWE Universe. Now, the Raw Superstar wants to share his enthusiasm for cars, and help the family of a longtime friend in the process.

Cena and his brother, West Newbury, Mass., Police Department's Sgt. Dan Cena, will once again oversee the raffle of a muscle car to help the family of Kenny Fowler, a firefighter who died in December 2007.

On Saturday, Aug. 14, Cena will appear at Pentucket Regional High School in West Newbury to sign autographs from 11 a.m. to 1 p.m. Then, with his brother, he will oversee the raffle of a classic 1969 Chevy Chevelle. All proceeds from the event will be donated to the Kenny Fowler Foundation.

Tickets to receive an autograph must be purchased in advance between 9 and 10:30 a.m. on Aug. 14. The cost for a signed photo is $15. Only a limited number will be sold and no personalized items will be signed. Raffle tickets for the 1969 Chevy Chevelle cost $100 per ticket. Only 500 will be sold.
