What is Vehicle Health Score?
A vehicle health assessment evaluates your car across mileage, service history, state inspection results, wear indicators, and overall condition.
The Formula
Score = (Points Earned ÷ Maximum Points) × 100
Worked Example
A 5-year-old car: mileage 7/10, service history 9/10, inspection 8/10, wear 6/10, condition 7/10.
- Total = 7 + 9 + 8 + 6 + 7 = 37
- Maximum = 50
- Score = (37 ÷ 50) × 100 = 74%
📌 Vehicle health is 74%, well-maintained with full history but tire and brake wear suggest upcoming maintenance costs.
Why This Matters
Maintenance planning
Identifying wear items early allows planned maintenance at 30-50% lower cost than emergency repairs.
Resale value
Vehicles scoring 80%+ retain 20-30% more resale value. Documentation and condition directly impact buyer confidence.
Safety assurance
Regular health checks catch safety issues (brakes, tires, suspension) before they cause accidents.
Common Mistakes
❌ Ignoring service intervals
Skipping services saves short-term but causes 3-5x more expensive repairs when small issues compound.
❌ Inspection pass equals healthy
A state inspection pass means minimum legal standard. It does not check many components that affect reliability and value.
❌ Mileage-only assessment
A 100K-mile highway car may be healthier than a 40K-mile city car. Driving conditions matter more than mileage alone.
