Gidday mate. Presumably the '120k' means 120,000kms, not miles? You might usefully include year, number of owners, and any significant work done on the car. Even then, I doubt you'll get much guidance - it's a fairly rare beast and most prospective buyers would consider what you're asking and then decide what they'd be willing to pay relative to the asking price. Have to say that the need for a new driver's seat and instrument panel would put me off, quite apart from the paint issue. The car would, I suggest, be much more saleable if those things had been sorted first.
