Just to add my 2c worth here, I think that if you haven't seen this car in action then you can't really put a value on it. And that's not a dig an anyone folks. This has top be seen and sold for what it is, not what it looks like. Why IS Rubie Hill called Rubie Hill - buy this and you'll find out. But only if your nerve matches that of the current driver.
This is not an old battered 80 with some bits. It's waay more than that. It's the Pride of Lincomb.
As to value Ian, obviously you can't price nostalgia, but you can price the work and parts. If you wanted to recreate this you'd need to start with a base vehicle at what, £4k? Then add all the bits. Well you'd be into £6k in seconds.
If someone wanted to make a replica of this, they would probably have unbent panels wouldn't they? How long would they last doing what it was built to do. Look what happened to Muxley! You might as well start with a battered one and save the grief. I have never seen anything like this off road and it's what got me wanting an 80 so bad. Seeing it go up the steps like they were a car park ramp kept me awake at nights.
Hey, you could rent it out!
