"The Eunos can be had for much less than any of these cars from the same era as well. $5,000 Australian should give you a good example."
$5,000 for car with astronomical mileage of 250,000... Gosh... Speechless... Someone... pass me a paper bag, please..
I have 4 Eunos 500s (not counting 800s):
1. 1996, 180K, bought with 3/12 rego left, paid $495.
2. 1997, 165K, rego expired when bought, paid $500.
3. 1998, 92K (yes, 92K), rego expired, paid $750.
How, under the blue moon, did the author managed to pay $5000 for a car with 250,000km and lots of problems due to high mileage (a worn stick is a good sign of a big mileage) - beats me.
Also - Mazdas have the shortest engine lifespan of all Japanese cars, beaten only by Mitsubishi (it always surprises me how Mitsi can build good truck, but never a good car) so 150-180K is an absolute top for them. If you see 200-250K - run away. No matter how cheap. At the end of the day it will cost you more in repairs and faults than a low mileage example.
A note on so called "service history": Service history IS NOTHING. MEANS NOTHING. Tells you nothing. All it means is that once in a while the long-eared owner drove into the workshop to be robbed by happy mechanics who might or might not do anything to the car. It is only a dealer's gimmick to fork out more money when they sell it.
I worked as a mechanic for years, and I know what this "service" is worth. A quick oil change, done by a useless acne-covered apprentice with his hands growing from his butt, with 10% of the old dirty oil still left inside, MAYBE an oil filter change (if it is easy to get to), never a plug change (you're lucky if the oil plug thread is not cross-threaded), and topping up the coolant with the cheapest Chinese chemicals, all done in a rush. And I worked for Volvo!
Owner history is more important. If you buy from a boy racer, you will regret it. If you buy from a lady, or even worse, from a girl - it probably all depends on her boyfriend. How useful he is. I saw a 240 Volvo brick (a potentially indestructible car) being ruined by a girl's useless BF, who was an apprentice mechanic. He overfilled the car with oil so badly that oil got sucked into the engine ventilation system, resulting in oil filling up the cylinders.
If you buy from an OLD lady, then you are a winner (provided she didn't have a boy racer grandson who stuck his busy little hands under the bonnet).
