Hi Richy,
if it runs and drives, then it should not take too much to get it back on the road. My advice is to get it back on the road and give it a good blast, if you come back with a smile on your face, then keep it. If not, then it will be time to sell it. Most CS's I've seen only go for about £1500 or there abouts. If you can, get over to JAE and put another crate on the stand.
Hope that helps.
