MANCHESTER — Rarity adds to the appeal of classic and specialty cars, and the public can view them up close Saturday at the fourth annual Union Leader Salvation Army Santa Fund Show 'n' Shine.

Dick Pellerin, of Hooksett, will bring his supercharged 2007 Roush Mustang to the show at the New Hampshire Union Leader, 100 William Loeb Drive, Manchester.

Pellerin's torch red convertible with red and gray interior is one of 14 made to the same specs, he said.

Appearing last year were a 2011 Tesla Roadster 2.5, owned by Steve and Sheila Sanders, and a 1919 Ford Model T, owned by Guy Hastings. “We hope to see him again this year,” said Norma Boyce, the show's founder and financial controller for New Hampshire Union Leader.

Boyce's husband, Herb, has a 1935 Ford Street Rod, and she owns a 1966 Ford Mustang GT.

“People love to show off their cars, and other people love to look at them,” she said.

Representatives of New Hampshire Motor Speedway will offer discounted tickets and information about the track's upcoming vintage racing and old-fashioned car shows. The track's pace car will be on-site.

“It's nice to have New Hampshire Motor Speedway on board,” Boyce said.

Awards will be given for the best car of each decade and for best of show. Food and beverages will be available at the event, which will also feature music.

Superior Interiors will sponsor the awards for the fourth year.

Admission to enter a vehicle is $20, and spectators are asked to make a donation to the Santa Fund. Registration is from 8 to 9 a.m., and the event will run from 9 a.m. to 2 p.m. Rain date is Saturday, Aug. 11. For more information, contact Boyce at 206-7752.
