quad, so best to go and put on rolling road like you, thats a massive performance gain on that curve your at origional bhp at less than the running in 4500 rpm, and such low rpm torque . How do you go about servicing and wrty if bmw see that they will flip? I would rather have a hybrid, a box tested on the rolling road but something I can unplug when I need to hide it.
Also Some give a wrty on engine, gearbox, clutch hand break issues if bmw do not pay up.
quad just seen your photobucket images, like the shopping trolly / carport. See u have a spiced up mini. My godfarther who is a mechanic had a mini 35 years ago stuck a v6 in the back. well funny.
