What is a 200-Point Car Inspection and Why is it Important Before Buying or Selling?
An in-depth look into automotive diagnostic inspections, explaining how multi-point audits detect concealed flaws and establish fair vehicle valuation.
Comprehensive mechanical, electrical, and structural engineering audit.
Exposes hidden head gasket blow-by, gearbox synchro wear, and chassis putty.
Certified technicians visit your home with digital paint and OBD-II tools.
1. Why a Casual Test Drive is Never Enough
A 5-minute test drive around the block cannot reveal blown head gaskets, dormant ABS sensor failures, or non-factory chassis welding behind bumper covers. A diagnostic inspection lifts the car, measures brake pad thickness, evaluates tyre DOT dates, and scans the internal computer.

2. The 200-Point Inspection Architecture
The diagnostic audit systematically examines 6 core subsystems:
- Engine & Powertrain: Cold start compression, oil blow-by, turbo spooling, and transmission fluid condition
- Structural Chassis: Aprons, radiator core support, A/B/C pillars, and floor pan welds
- Exterior Body & Paint: Digital micron paint depth measurement across all panels
- Electrical & Electronics: Full ECU OBD-II trouble code scan and live sensor stream
- Suspension & Brakes: Disc rotor thickness, pad wear, strut leaks, and control arm bushes
- Documentation: Original Smart Card RC, chassis pencil print, insurance claim history, and e-challans
3. Digital Paint Depth Testing: Catching Hidden Body Filler
Factory automotive paint measures between 90 and 130 microns. Repainted panels show readings between 160 and 220 microns, while accidental panels filled with body putty and Bondo exceed 300+ microns, immediately exposing past collisions.
4. Pricing Leverage for Buyers & Sellers
For sellers, a certified inspection report with high scores justifies a premium price. For buyers, the report provides factual leverage to negotiate discounts for any routine wear items that require maintenance.
