That happy little jingle you hear these days emanating from your favorite auto body shop is probably the owner, because right now is certainly his Most Wonderful Time of the Year.

Each November, cars come towed or crawling into garages with front ends compressed like accordions, windshields demolished, side mirrors ripped clean off the doors.

Jason Caldarone, who manages Charlestown Auto Body, has seen cars arrive at his Route 2 shop with their roofs peeled back like tin cans and clumps of fur hanging from all the sharp edges like some gruesome salutation of the season.

“Last year we had a brand new Trail Blazer come in,” he says. “The deer went down the whole side, wiping out the grill, the bumper, two doors, the side view mirror and the quarter panel. She [the driver] says it just came out of the woods and plowed into her. She told me, ‘I was looking at the thing in the teeth.’ ”

Repair cost? $9,000.
