One observation regarding the kms - there's way more to a vehicle than simply the engine, to state the obvious. At those kms there are many other parts that may or may not be nearing the end of their life, and the issue then is not just $ but reliability. Personally i wouldnt buy a car with those k's at tgat price. I know its toyota, but they are not infallible. Even if you have looked after it impecably, potential buyers wont know this. I really think the mileage will be the limiting factor even at $25k. And age. Not trying to have a go, but i would have traded it myself. Hope it goes well, as said above i would take the 1st reasonable offer -anything above $20k maybe.
