Mate of mine in Bristol got a BMW330i recently. Just back - had a spin yesterday. It had a tip gearbox which I didn't think much of - time lag between lowering the right shoe and anything happening seemed forever. Brakes were dead sharp though - vented discs front and rear - nearly went out through the windscreen when I tried them!
Can't remember what he said the HP was - 260 maybe - didn't feel anywhere as lively as a manual GPX though
