• Year‑to‑year decline: averages 4‑6% annually once the initial depreciation curve flattens
• Long‑term value retention: well‑maintained examples with complete service histories tend to hold 30‑35% of their market value beyond a decade
• Annual rate of appreciation: rare and well‑preserved 1980 variants may gradually climb 5‑7% per year, driven by increasing nostalgia and improved restoration techniques
• Risk factors: rust, incomplete documentation, or missing original parts can reduce value by as much as 25‑40%
