Danny Koker shows off 5 ultimate muscle cars designed to make a mark. The Ringbrothers take an old 70's AMC Javelin and give it a thousand horsepower makeover! In Detroit, we meet the Equus Bass 770--an all-new bespoke built machine that takes the best of American muscle and runs with it. In Wisconsin, we get car maintenance tips from Grace who's been driving her classic '57 Chevy Bel Air since she bought it in 1957! Later we tear up the roads of California with Vicious, the million-dollar Mustang.
