1995-2001 Ford Explorer/Mountaineer 2WD
1995-2004 GM Blazer/Jimmy/Bravada 2WD
Built on solid small truck platforms with excellent parts availability, but without the pickup price tag. Have seen both platforms with over 300K miles pretty frequently. Much better hauling ability than a sedan, roughly 20 MPG highway, simple to work on, low resale/desirability, etc.
The downside is both are prone to rot up north, and sometimes get brought down from up north in that condition when they can't pass an inspection anymore.
Of course, at $1K, take whatever is cleanest in that budget. This is just a suggestion for vehicles that might offer some kind of bang for the buck in that range.
