Just wanna throw it out there, but check the front brakes. A lot of us, myself included, had the dragging pads noise for the first few hundred miles. THere's a ton of post on here about the "hum" or "squeel" from one of the front wheels. I'd be willing to bet that's what you're hearing. To save you some post searching, it most notably occurs with warmed up brakes, at low speeds, or just off a stop light, or pulling into a parking space, clutch in or out, and is temporarilly relieved by touching the brake pedal or jerking the steering wheel in one direction or the other. Mine pretty much went away on it's own.
