Report shows used BEVs now have a Market Days’ Supply (MDS) of 52 days which is behind petrol cars at 46 days and hybrids at 53 days. Market Days’ Supply is derived from dividing the currently available supply of inventory by the average daily retail sales rate over the past 45 days. The UK continues to have the lowest EV MDS in Europe, well ahead of the European average of 85 days.
