The used car market is suffering from stock shortages at the moment. Over the past three years, the sale of new cars has been falling (which means fewer people have been part-exchanging their cars for new ones). Pandemic-related lockdowns over the past 12 months have also disrupted the supply of new cars, which means people are holding on to their vehicles for longer because they are waiting 6+ months for their next car. Prices are rising and cars are selling very quickly. This is bad news for buyers because everything on sale is being snapped up by dealers and drivers. I think it will take a minimum of 12 months for things to return to normal.
