Yeah, I bought the GQ wagon after a nice long drive to Narromine from Canberra area and the GU wagon after driving to Brissie. Mind you, I do like a road trip....Being it's a TD42 over a TB42 and the condition it seems to be in, I would be making the trip and checking it out and then making an offer if all is in order. The engine alone is worth $5000. I bought my 89 TD42 fr $5000 but it wasn't well looked after (with 420K on the clock) and I have put a good 2 grand into it, so it cost me about $7000.
The fact it's out of rego or will be soon and the fact it's a 25+ year old car I would use those a points when making the offer. I think it's worth $10,000 if there isn't anything too major wrong.
If you have the cash I wouldn't let her pass you by without at least having a look. I traveled 3 and a 1/2 hours for mine and bought it, for the right vehicle you need to be willing to make the trip.
