Hardware specs, model metadata, benchmarks, prices and calibration are separate datasets. The bundled JSON files in /data are the source of truth; edits here are an overlay stored only in this browser.

Price database

Typical US prices in USD. Missing regional snapshots use a clearly marked Swedish price converted at ECB euro foreign exchange reference rates (EUR/SEK 11.2425 (2026-10-06). Browser edits save New and Used separately; a blank field in a newly edited market remains unknown.
