Certainly trade prices are crashing right now. Down 4.2% last month which is the biggest monthly drop in 12 years, and down 13.6% since April. CAP are predicting another 10% drop by the end of the year. The problem is a lot of dealers are hanging onto old stock they bought at a higher price hoping things will pick up, so the drop in retail pricing has not been as big.
Give it time though I think we’ll see big drops as the lower prices filter through. A 2021 RX450H with 9k miles popped up on AT the other week for £33K, obviously fresh from the auction bought at a lower price, it did sell but then it was 7-8K lower than the other overpriced ones that have been sitting around for 6 months.
27K for a car coming up for 8 years old seems an awful lot, as someone else said put the reg into wbac to see what that quotes and view it as a trade price. A garage might expect 3-4K margin at that price, so it will give you an idea.
Also install the AT price plugin on chrome, it will show you the historical pricing the garage has tried to sell it at and how long they’ve had it.
