I love the driving dynamics, and potential for 420+whp and 450+wtq with just a few bolt on parts. N54 FTW!
I love how when I poke fun at my Infiniti, Lexus, and Audi friends that they drive overpriced Nissans, Toyotas and VW's, they can't counter because our cars are built from the ground up with top tier components, not parts, engine or a chassis shared with an econo car.
You can feel the platform and component sharing when you drive ther other guy's luxury brand, a G37 feels like a sporty Altima, an IS350 feels like a sporty Camry, an A4 feels like a sporty Jetta. You don't get that feeling in a BMW, everything feels unique to BMW, steering, brake, ride, handing, engine ect.
