From talking to traders the impression I get is that the right combination of car (spec, colour, engine) seem to be selling well, but anything less desirable may struggle. Every car will sell at a certain price but it's just a battle to still fit a margin in between the two. I also think that new car pcp's are affecting the used car market, as it is so easy for a dealership to keep refreshing a customer into a new car cycle. Especially with the difference in new car APR compared to used.
