Too many variables:

- present condition?

- documented service history?

- original engine and transmission?

- steering and suspension work?

- are you looking for a keeper or something to make it through the winter?

- are you looking for something to drive into the ground or resell?

- are you a DIYer or will you pay someone to keep it running?

Typically resale value starts to taper at 150K miles, drops faster above 250K miles, you basically have to sell it for parts beyond 350K miles. That's my observation. There are many exceptions. There are cars that are in superb shape beyond 350K miles but most buyers see the odometer and shy away.
