If you're looking to give your Mercedes-Benz an added dose of performance, look no further than Brabus. The aftermarket tuning house specializes in customizing Daimler's finest, and doesn't stop at upgrading the engine and running gear, either. With packages like the iBusiness suite, Brabus will turn your S-Class, for example, into a 219-mph high-tech office on wheels. In other words, it'll make it more like a private jet. But what if you want your jet to feel more like your customized Mercedes?
