What is the make and model of a 2003 Chevrolet S-10 pickup?

The make is Chevrolet and the model is S-10. There's no further model designation beyond that for a 2003, as they didn't use sub-model names like "ZR2" or "Canyon" in the same way later trucks did. The specific trim level (like LS, WT, etc.) would be additional information needed for a complete description.
