As Brookesy said check the sill's out side and inside,battery tray,front suspension mounts,boot floor,chassis rails and bottom of the door's for rust thats the main proberm on a xr2 also make sure the engine is running sweet no sludge around the oil cap
You should get a good one for around £700-£800
