The 70% BMW scrap threshold is based on 2025 UK enquiry data [EM-VERIFIED]. For rare, collectable or low-mileage BMWs, the recommendation may differ — consult a specialist.
The calculator applies the 70% BMW scrap threshold — if the total repair cost (including labour) is less than 70% of your vehicle's current market value, repair is recommended. If it's between 70% and 100%, watch — consider a second opinion and compare replacement costs. If it exceeds 100%, scrap or part-exchange is usually the better financial decision.
For a deeper dive, see our Decision Framework page with worked examples. Use our engine value checker to see what your engine is worth, and our replacement cost by engine code for more precise figures.
