After more than three decades of television success, Tim Allen knows a thing or two about building a hit sitcom — and yes, he’ll take some credit. His latest series, Shifting Gears, is another ratings winner, this time pairing Allen with Kat Dennings in a comedy about family, estrangement, and, of course, classic cars. The show was recently renewed for a second season by ABC, and Allen has told Closer Weekly that bringing his own passions into the series made it a winner in his eyes.
