If you go to look at it ask if you can take the valve cover off and look at the valve train. At the very least pop the distributor cap off and see if the points internals are there, smell the oil, try to turn the engine over by hand. Then pop the gas cap off and smell. Siteunseen is right, most people lie, forget, or just don't know why a car does not run. If it just needed a fuel pump, on a difficulty scale of 1-10, it ranks around a 2. Easy for you but also easy for the owner, why haven't they already replaced it? The Datsun I-6 is a very durable engine with many documented cases of successfully waking them up after many years of non-use. With that in mind, check out the thread link on waking up an old Z car. On classic Z's the mechanicals are fairly easily to deal with and reasonably priced. Rust and missing odds and ends will eat you alive. If the car is in good shape body wise, interior is good minus the missing shift knob, and the engine appears sound, then make an offer. $2K - $3K is not unreasonable or insulting. Solid running early 240z's in good but not perfect condition start at $7K and quickly go up with an average $12K - $18K so you could end up with a heck of a deal. If you do get the car you are looking at be prepared to be patient and diligent in going through all the systems to make it run again. Keep up posted and give us some pictures! Good luck. http://www.classiczcars.com/topic/21063-waking-the-sleeping-beast/
