Five-Year Depreciation Leaves Alfa Romeo Giulia Quadrifoglio Near $43k Used Price

Kelley Blue Book data show the 2021 Alfa Romeo Giulia Quadrifoglio has depreciated about 44% over five years, bringing its current resale around $43,000. By comparison, the BMW M3 retains about 83% of its value (roughly $58,600), while the Mercedes‑AMG C63 sedan sits at about 41% loss (~$41,400). Despite reliability concerns, used examples remain desirable and prices have inched up in early 2026; the Quadrifoglio was discontinued in the U.S. in 2024, yet demand persists.
