In a market where realistic Mercedes-Benz SL-Class price insights guide both newcomers and seasoned collectors, understanding the value dynamics—especially for heritage years like 2004—becomes essential. Below, we break down the specs that define the SL-Class, clarify Mercedes-Benz SL-Class depreciation, and answer the age‑old question: what is a 2004 Mercedes‑Benz SL-Class worth?

**Mercedes-Benz SL-Class depreciation** is a key topic for any prospective buyer. While luxury vehicles traditionally maintain higher residual values than the average passenger car, the SL-Class still experiences a noticeable decline shortly after purchase.
Typical depreciation rates:

• First year: 15‑20% of its new‑car price.
• Second year: an additional 8‑10% drop.
• By the third to fifth year: total depreciation often exceeds 30‑35%.
• After ten years: resale values generally hover around 50‑60% of the original sticker price—assuming a clean, well‑maintained vehicle.

These figures represent typical market behavior; actual results vary with mileage, condition, provenance, and regional demand. For example, a 2004 SL-Class that has undergone full service history checks, has low mileage, and is presented in a controlled climate can command a resale price on the higher end of the spectrum.

The Mercedes-Benz SL-Class price is inherently linked to its rarity and desirability. In a global database that tracks COE prices, such variations are displayed side‑by‑side: new
