Market Report
Triumph Stag Price Tracker
An interactive estimator, not a valuation. Pick condition, year, transmission, mileage and region, the tool combines the 2026 UK bands with disclosed modifiers. No invented auction data.
Indicative 2026 range
£15,000 – £22,000
Base band: Good usable driver (£15,000–£22,000). Combined modifier: ×1.00. Rounded to the nearest £250. Individual cars can and do fall outside this range.
How your selections change the range
| Factor | Selected | Modifier | Reason |
|---|---|---|---|
| Year / Mk | Any year (1970–1977) | ×1.00 | No year adjustment applied. |
| Transmission | Any | ×1.00 | No transmission adjustment applied. |
| Mileage | Not specified | ×1.00 | No mileage adjustment applied. |
| Region | United Kingdom | ×1.00 | Reference market; bands are UK-native. |
What this tracker is: and isn't
- It's an estimator: base bands from the Market Report adjusted by disclosed multipliers. Every modifier above is visible.
- It isn't a valuation. A single major issue, rotten sills, a snapped timing chain, a missing hard top, moves a car a full band regardless of the estimate.
- Provenance dominates. Documented history, both roofs, both keys and a matching-numbers Triumph V8 sit above the estimator; missing paperwork sits below.
- For a formal figure, use a specialist classic insurer's agreed-value scheme, see Insuring a Triumph Stag.
