but look at it this way, you would probably have to pay something like that for a semi decent low km Z anyway, as they are hard to come by with original km's on the clock.
Aus spec models are your best bet, as they generally have a good service history. If i had to hazard a guess, i'd say every single import has had it's km's wound back.
Aslo, although the aus-spec is almost entirely identical to a jap model N/A apart from some negligable differences, the insurance will be alittle cheaper as well.
Just remember it all comes down to what you pay for is what you get. $10K won't get you a very good condition car.
Alot of mechanics won't touch it either as half of them can't even find the air filter.The mechanics that do work on the Z will charge you a fair bit, but some do a very good job and know thier stuff (insert plug for UAS here).
Nissan will charge you through the nose for parts... best to hunt around for bits online or at the wreckers, or to buy aftermarket bits for it....
