Caterpillar M Series   Forget the BMW M3—developing Caterpillar's M-series industrial road-grader involved more than 100,000 hours of field testing and input from more than 900 customers. The result gives the working man (good to know there are at least 900 of those left in America) a much needed break: The back-breaking array of levers and knobs employed by the previous model has been replaced by two video-game-style joysticks. Finally, a (legal) career where playing GTA counts as job training.   Caterpillar M Series Motor Graders, price upon request, cat.com
