| Vehicle Value | Recommendation | Reasoning |
|---|---|---|
| Under £5,000 | Used engine (or repair) | Replacement cost may exceed vehicle value |
| £5,000-£8,000 | Evaluate both options | Reconditioned viable if keeping car 2+ years |
| £8,000-£15,000 | Reconditioned (or rebuilt) | Warranty justifies £600-£1,000 premium |
| £15,000+ | Reconditioned or rebuilt | Replacement cost small relative to vehicle value |
