Both valuations offered by We Buy Any Car and Motorway are relatively accurate because they use live market data to track the value of multiple car models and makes, ensuring you're quoted a price that reflects these trends.  As you can adjust and input your car's condition when getting a valuation from We Buy Any Car, their valuation will likely be more accurate, especially as Motorway's valuation assumes that your vehicle is in excellent condition.  That said, once you list your vehicle on Motorway, the offers you receive from their partner dealerships will be the most accurate to its current value. Your final offer will typically be closer to this amount as well.
