We'll 100,000km is really a milestone for any car. They're just a little older, and i guess that equals more wear and tear. There are still a few examples out there with less kms going for more money. Going by that most ppl just price accordingly. It also depends on colour and individual condition. I mean if was going to sell mine id aim as close to $40K as possible, keeping in mind its white, done less that 70,000Kms, service history and plenty of mods.
It depends on the overall car not just the kms, but the higher the kms, the lower the price, just like any car. Doesnt always mean it will fall apart on you.
