Saloons don't sell well at all so you can knock £500 of it to start with. Plus it needs paint, mirror sorting and doesn't have warranted mileage.
If I was doing it as a p/x clearance I wouldn't want to give more than £600 for it. If it was straight, it would probably go out at £1000+ a bit depending on condition etc.
On the plus side though, it is a Ghia so reasonable spec.
