I can't help thinking that the sensible thing to do would be to get your car weighed. Even if the official figure s within the weight limit of your trailer, it's the actual weight of your car that important, not what the manufacturer claims it to be.
But having said that, 950kg sounds about right, maybe a little high. My 4/4 weighs 860kg in road-going trim (all fluids, half a tank of fuel, no driver)
