Handling and Reputation:
Handling: The 999S is lauded for precise, sharp steering and superior maneuverability, with many finding it easier to handle than its predecessor, the 998.
Performance vs. Base: The "S" model is essentially a race-derived version of the base 999, featuring a remapped ECU for better power delivery, in addition to the premium suspension.
Known Issues: Potential buyers should check the wiring harness for corrosion (especially near the battery/fuel pump relay) and ensure the top-end service (Desmo) has been performed, say.

The 2003 model year marked the debut of the "S" variant following the initial launch of the 999 series, making it a desirable "first-year" iteration for collectors.
