Yeah there will be a passenger, tools, spare wheels/tyres, fuel, plus luggage etc. I won't be changing the current car for another year at least so it's a while off. I do like the idea of an M50d but a) I don't really want a diesel and b) I don't really want an SUV. Whatever I get will have to be my main car and I don't want a 4th car on the drive just to tow with!
