The rule "if it doesn't sell it's too much" seems to have gone out the window, for all marques and ages. Hardly anybody is buying cars, either becuase they can't get finance, or they have more mundane things to use the money for or they are just sitting on their money and riding out the storm.
Honda, Jaguar, Nissan, Land Rover, Mini & Vauxhall have cut productions lines, either losing the night shift, losing overtime or shutting down the factories for 2 months. Germany has gone into reccesion because car sales are so low (it's one of three reasons).
If you can afford to hang on then don't sell yourself short.
