Is the price quoted by the used car valuation calculator accurate? 

Yes, the price quoted by the used car valuation calculator is quite accurate. Reliable calculators are programmed to consider several factors when calculating the price. These include the current value of each car so that it can be manipulated as per the information you provide. 

However, the price quoted by the seller or the dealer may differ from the price estimated by the calculator to a certain extent as there are many other factors to be considered when it comes to the actual sale. The calculator is a useful tool to get a fair idea of that price.
