Understanding the Triumph Stag depreciation curve is essential when evaluating used Triumph Stag price. Classic cars generally trade more slowly than modern market vehicles, but initial depreciation can still be significant.

Depreciation Insight

• First year loss: Typically 15‑20% of the purchase price, reflecting initial market oversupply and new‑car discounts.
• Year 2‑3: Value stabilizes, often retaining 70‑75% of the original price if the car remains in good condition.
• Long‑term appreciation: From year 5 onward, well‑maintained Stags can see a 2‑5% annual gain, especially if kept in low mileage and proper restoration quality.

While depreciation is a general rule, each Triumph Stag’s journey depends on factors such as mileage, mechanical condition, originality, and provenance. Vehicles that stay under 20,000 km and receive professional servicing often hang out near the lower end of the depreciation curve.

Comparison Context

It’s helpful to place the Triumph Stag within its peer group. Compared to contemporaneous models such as the Lotus Emira and Datsun 240Z, the Stag offers a larger displacement and a smoother inline‑six experience with the added benefit of traditional British styling.
