A used car can look immaculate in photos and still hide expensive problems. A structured pre-purchase inspection turns "it looks fine" into a documented assessment of more than 160 individual points. Here's how a professional inspection is organised, and what each section tells you about the car.
Before you start: documents and identity
Match the car to its paperwork first. There's no point inspecting a car you can't legally register.
- Chassis (VIN) number matches the RC and is not tampered or re-stamped.
- Engine number matches the RC.
- Owner name, fuel type, registration date and RC type are correct.
- Insurance validity and claim history reviewed.
- Hypothecation status — is there a loan still on the car?
- For CNG cars: endorsement on the RC, kit type and validity.
1. Exterior body and paint (≈40 points)
This is where accident history hides. The inspector checks each panel — front bumper, bonnet, grille, both fenders, all four doors, quarter panels, roof, tailgate and rear bumper — for:
- Condition — dents, scratches, cracks, rust.
- Repaint — has the panel been resprayed?
- Paint depth — measured in microns; factory paint is consistent (typically ~100–130µm). A panel reading much higher has been repainted, which usually means damage was repaired.
- Company-fitted — are doors, bonnet and tailgate original or replaced?
- Windshield and glass — original vs replaced, cracks and chips.
- Headlights and tail lights — fogging, cracks, moisture.
2. Structure and frame (≈15 points)
Structural damage is the most serious thing a used car can hide because it affects safety and is expensive to fix correctly. Inspectors examine:
- Upper and lower members (the front frame rails).
- LHS and RHS aprons.
- A, B and C pillars on both sides.
- Fender walls, cross member, dicky/boot tub and tailgate frame.
Welding marks, crumpling, fresh underbody paint or non-factory fasteners in these areas point to past structural repair.
3. Engine bay (≈12 points)
- Oil leaks around the block, gaskets and sump.
- Engine oil condition and level.
- Coolant and brake fluid levels.
- Battery condition and age.
- Belts, hose pipes and wiring for cracks or rodent damage.
- Engine mounts.
- Firewall for rust (a flood indicator).
- The MIL / check-engine light behaviour on ignition.
4. Interior and electricals (≈25 points)
- Dashboard, glove box and trim condition.
- Music system, speakers, steering controls and paddle shifters.
- Air conditioning cooling and all vents.
- Power windows, central locking and the boot/fuel-lid levers.
- All lights — cabin, headlights, wipers and rear wiper.
- Steering type, cruise control and navigation where fitted.
- Seats — front and rear condition, adjustment (manual/electric) and seat belts.
- Rear seat arm rest, AC vents and side panels.
5. Tyres and wheels (≈20 points)
Each of the four tyres plus the spare is assessed for brand, wheel type (alloy/steel), remaining life and an estimated replacement cost. Uneven wear across tyres can reveal alignment or suspension problems — and a tired set of tyres is an immediate post-purchase expense worth thousands of rupees.
6. Road test and performance (≈12 points)
- Steering feel and self-centring.
- Wheel alignment — does the car track straight?
- Ignition and cold start behaviour.
- Clutch bite, gear shift quality and acceleration.
- Brakes — stopping power, pulling, vibration.
- Suspension over bumps.
- Engine noise — normal, knocking or vibration.
- CNG mode performance, if applicable.
7. Photo documentation
A proper report is backed by photographs — vehicle from all four sides, dashboard and odometer cluster, driver and rear cabin, boot, engine compartment, firewall, battery, chassis plate, and each tyre. Photos let you (and any future buyer) verify the condition without relying on memory.
Putting it together: ratings
The hundreds of individual checks roll up into clear ratings — interior, exterior, engine, test drive, structure and electrical — plus an estimated repair cost. That summary is what turns a long checklist into a buy / negotiate / walk-away decision.
Should you do this yourself?
If you have mechanical experience and a paint-depth gauge, you can work through much of this list yourself. But paint depth, structural welding and engine health are easy to miss without the right tools and a trained eye — and a single missed accident repair can cost far more than a professional inspection. For most buyers, a neutral third-party inspection is the cheapest insurance available.
