Gale Banks and Adam Carolla talk Diesel and Big Diesel power. We get into some talk about algae and alternative energy sources. Then Sandy (The Professor) and Adam take on another week of Investment Cars. Next onto Skype calls... NOS and Tombstones? You Figure it out. Then the CarCast crew head out for a quick trip to the Palos Verdes Car show to check out a special work of automotive art, the Maserati Tipo 61 'Birdcage'. And the wrap up with Doug Benson's first car.
