- Compare to Averages: Brakes £127, clutch £500–£1000 (Payment Assist). Use estimators like Openbay for benchmarks.
- Check for Overcharges: "Book time" scams inflate reality (Scottys)--e.g., 0.7 hr tie rod billed higher with multipliers (RO Writer).
- Review Warranty Details: Ensure parts/labor covered (Carfax: 50% risk reduction with certified shops).
- Get Pre-Approval in Writing: No verbal OKs--protects against escalations like Sarah's story (OreateAI).
