Yes basically the chap who bought it off my Dad drove it once then had a health problem and couldn't drive it anymore. He left it in the garage under a bunch of stuff for 18 years. My Dad with the help of the DVLA managed to contact the owner and buy it back.
The engine turned over and with the help of my brother they managed to get it running again.
Here is a video of when they first managed to get it running again...
