I actually said to my g/f that I thought it would go up to about $22-23k. It was a good car - no rust apart from that spot in the roof which had some minor bubbling (I couldn't climb under it or get it on ramps etc..). Not sure when the car was restored but the paint was still good. It did look a lot nicer in person (the colour) and the wheels I didn't mind since they were looking as they should - I have the same set on my Gold 70 240z and after seeing that car I was thinking I could live with them if they were painted up and presented right (at least until I can afford something nicer).
The interior was for me the biggest let down, the re-trim job was average at best and not my cup of tea. They replaced the headliner with some god awful stuff - would have been better to keep the door cards, carpets and my favorite the diamond vinyl trim etc.. all stock.
The auto was a let down (well for me I don't like them in Z's) but mechanically she sounded sweet and it had the original exhaust manifold - which is quite rare for a 240z!
When I fired it up a few young fellas with their father (I think) were around it and comparing it with early Mustangs etc.. the sound of the L6 firing up put a big smile on their faces and mine.
There were some other little customisations that were not my bag, but mostly easily reversed.
The rear hatch and passenger door alignment were a little out, I thought it was possible the rear had a minor tap at some stage due to the placement of the paint chip in the wheel well (as if something had pushed it or stretched it causing it to flake off ). However the paint inside the car under carpets etc.. looked original and even though the brown is probably not the best looking colour on the 240z, the fact that a previous owner kept it original at time of it's last repaint said something about the way it had been looked after.
At the end of the day, this was a car you could get in and enjoy right away. You could easily spend that money restoring a rust bucket and not even be done with the body work yet. I'm sure a few people here could verify that claim also!
Unfortunately I didn't get to check for matching numbers but I don't think it matters that much, well at least the price reflects that.
The 240z didn't look out of place in amongst all the other high end cars in there and I was kind of happy to see an old brown 'Datsun' in amongst them.
Best of luck to the new owner and I hope they join up here and share it with us. Be a shame for it to be hidden away again.
