The Repair vs. Sell Financial Formula
Deciding whether to fix or sell an aging car is a common dilemma for Brisbane drivers. Consider these rule-of-thumb principles:
- The 50% Rule: If an estimated mechanical repair bill exceeds 50% of the car's market value, repairing is generally financially unviable.
- Registration Expiry: Renewing Queensland registration on an old car with mechanical faults adds $700–$900 in costs before accounting for repairs.
- Safety Certificate Risk: Old vehicles often fail RWC inspections due to worn suspension bushes, oil leaks, brake wear, or headlamp haze, requiring compounding repair costs.
