01 Prism high mileage

I need to buy a car and I found this 01 Prism for about 3000... but it has 170 000 k on it and had only one owner. I know it has a Toyota engine, but I can't decide if it's worth it since it has so much mileage. Can anyone give me a piece of advice on this issue? thanks

If it's got that much mileage on it and it's running good, it's obviously been taken care of. How many miles do you need to get out of it? It's a good car overall.
