Discovery's new unscripted series, 'Sticker Shock,' is answering the one question we all want to know, "What's my car worth?" Appraisers on the show, Nick Smith and Todd Wertman, inspect a 1948 Bentley and a 1957 Chevy Bel Air. They sat down with Cheddar's Alyssa Julya Smith to tell us how they determine the value of these antique cars.
