Nothing wrong with high milers if there looked after properly but you have to take into account the wear and tear on all the other bits not just the engine.
The old jap plastics can suffer over time if care isnt taken and the seats can also wear. Then theres the running gear etc
None of this is a show stopper aslong as its reflected in the price.
If its going to annoy you though and you end up replacing bits over time then you have a car that could cost as much as a low miler with high miles on it.
Its always the same, spend as much as you can and get the best condition with the lowest miles and you likely get a nicer car..
if you just want to have the zed experience and not looking for long term ownership it could be more prudent to buy a cheap one and move it on after a short while.
