Yes - as reported in all the motoring press, there has been a big increase in the price of second hand cars.
In June I bought a 2.5 year old 68 plate Jazz EX Navi from a Honda franchise dealer. It was one owner, sold originally by the same dealer and had a very low milage, possibly due to Covid travel restrictions. It was in "like new" condition.
Looking on Autotrader today, low milage cars of the same age and specification, from franchised Honda dealers, are all about £3500 - £4000 more than I paid - and these cars are now slightly older than when I bought mine. Higher milage vehicles, and cars from non franchised dealers are also around £2500 - £3000 more.
Like Philno, it is the first time I have ever bought a car that appreciated in price. The downside is that if you have any thoughts of instant "profit" either the new car you want may not be available (which is why prices are up), or the second hand car you want instead will also have had a big price increase. There ain't no free lunch
