That sounds about right, my 4X8 trailer weighs 460lbs and has a 1450lbs capacity. If your trailer and load combined stays under 1500 then you are within the acceptable limit. No usa cop is going to even think to consider the tow rating of your car. I will say that years and years ago I towed an 1100lb. boat and trailer with a 1970 Valiant and it almost overpowered the brakes, had to make long gentle stops otherwise it would push the car.
