The padel shift was done before I got the car, but is VERY easy to do - Involves simply fitting the steering wheel and then running from the back of the slip ring on the column 3 wires to the gear shift switch in the center console - About an hours work for a competant mechanic

Plans wise, Already looking at prices on the 4.6 M62TU engines as fitted to the X5 - they are somewhere in the region of 350bhp and a direct swap with no ECU changes
