You might find *some* parts are similar enough to work, but it's not guaranteed. You'll likely encounter fitment issues with things like:
* Windshields: While the general shape might be similar, the curvature, mounting points, and even the seal may be different.
* Doors and Body Panels: These are highly unlikely to be interchangeable due to changes in body styling and dimensions between model years.
* Glass (windows): Similar to windshields, the size and shape might be slightly different.
Before purchasing any parts, it's crucial to verify the part number compatibility with both your 2000 and the supposed donor 2003 Caravan. Using a reputable parts website with a VIN lookup or contacting a Dodge dealer parts department will give you the most accurate information. Trying to force incompatible parts can lead to damage.
