Difficult to say really, the market is all over the place at the moment and a lot of its value depends on its condition and history. With an MOT it might make £750-£1000 if you have long enough to wait for the right buyer. Without one, it's scrap value only for sure.
As a suggestion you might think about talking to Andy
@Clackers on this forum, he's not far from you. While it's still driveable he may be able to take it in and give you back a reasonable slice of what you've already spent on it. If he can give it a new lease of life from his parts stock, he'll fix it, he'll only break it if it's too far gone.
