It’s got to crash at some point, there’s going to come a time when joe public are simply going to find it cheaper to keep their current car running than pay these stupidly inflated prices of recent times.
As already said it’s only due to supply and demand at the min, no other reason. As soon as new car production it back up to speed and new sales are back up used stock will be fed back onto the market and the prices will come down.
This is why I’m being very careful with what I buy at the min. It’s feels very much like dealing with stocks and shares.
