Once an indicative valuation is generated we would ask the customer to send over as many photos or videos of the vehicle as possible so we can validate the price. The price can vary (up & down) dependent on damage, history, condition and other elements that the computer generated quote cannot take into consideration. We do as much as humanely possible to give an accurate part exchange valuation/purchase valuation prior to any handover taking place. It is very rare that this is altered, unless a mechanical defect is discovered on test drive.
