By 'average' I doubt very much that you mean Ferrari. Affordable, common, sports cars that are mass-produced could be expected to weigh ~1500kg.
To weigh objects on a scale, place the object you want to weigh on the scale platform. Make sure the scale is set to zero before placing the object. The scale will then display the weight of the object.
To weigh gold and silver in ounces, you can use a digital scale that is capable of measuring in ounces. Place the gold or silver on the scale and ensure it is zeroed before placing the metal on it. The weight displayed on the scale will then be in ounces.

To weigh mass accurately, use a calibrated scale or balance. Place the object on the scale and wait for the reading to stabilize. Ensure the scale is zeroed before weighing to account for any additional weight.
To weigh solid substances, you can use a scale specifically designed for measuring solids. Place the substance on the scale and make sure it is stable before recording the weight. Ensure the scale is properly calibrated for accurate measurements.
