All Part-Exchange valuations are provided as a desktop valuation and subject to full in-store appraisal. If your Part-Exchange valuation is £2,000 then this is guaranteed against the majority of cars in store. For all other Part-Exchange valuation amounts, the valuation provided is based on your car being in clean condition with service history and we reserve the right on full appraisal to adjust the amount by the cost of any cosmetic or mechanical repairs required or adjust values (up or down) based on market supply and demand dynamics
