We have a Mazda 6 and, last week, we bought eight acres of land for livestock farming, so we now need a vehicle capable of pulling a stock trailer, negotiating tracks and carrying loads such as bales of hay. Should I just put a towbar on the Mazda 6, which is our main car, or should I look for something different? What I don't want is a big 4x4 type car as it will also be used as our daily runaround and commuter.
