There is the right time to sell for the market, but there is also the right time to sell for the seller.
I'm not in it for the resale value, I'm keen to move the car on for a price I'm happy with to allow me to get on with the next car to replace it. At the moment the car doesn't work for me and my family, and I need a solution that does. So whilst I'd like to 'wait for the market to come to me' it doesn't make sense. So there are reasons that make sense to sell now and let somebody else enjoy the car.
The real oddity is the people who want to buy the car, those who talk and then go dark for no reason. It's the slog of selling that I really don't enjoy, and the market doesn't make it any more fun at all.
