Former "Shadetree Mechanic" and "Two Guys Garage" host Sam Memmolo, a pioneer in automotive how-to TV, is back turning wrenches and tightening bolts on "Sam's Garage." Memmolo helped develop the concept of step-by-step instructions to help advise viewers of the latest products and techniques for repairing and improving a wide variety of rides, a legacy that continues on his latest series. With vast automotive knowledge in the garage and in the studio, Memmolo is as entertaining as he is experienced. Sam Mahdavi also hosts.
