Following up on the success of its 15-second TV spot, “Modern Repair,” PreFab Ads is now licensing a 30-second version to auto body shops on an exclusive-by-territory basis. Set to an upbeat gypsy violin tempo, it opens with wacky, vintage footage of cars crashing, then cuts to repairs inside a modern body shop, followed by the sponsoring body shop’s logo. It’s the 15th auto body TV spot offered at www.prefabads.com. Call (415) 391-5030 for details.
