How to Verify a Used Car in Multan: The Complete Pre-Purchase Checklist

Used Car Buying in Multan & South Punjab: Practical Due Diligence

Buying a pre-owned vehicle in South Punjab often involves navigating informal roadside showrooms, commission-seeking showroom brokers, and conflicting verbal claims about a vehicle's mechanical condition.

Without objective physical verification, buyers frequently discover concealed accidental damage, repainted body panels, or altered digital odometers only after paying in full. This guide breaks down the essential checkpoints every prospective buyer must examine.

1. Document & Registration Verification

Before inspecting the engine bay, authenticate the legal ownership credentials:

• Excise Smart Card / Registration Book: Check the chassis number stamped on the vehicle firewall against the computerized excise database.
• Original File & Return File: Ensure original customs invoices or factory sale certificates are intact, especially for non-local registration numbers (e.g. Islamabad or Karachi numbers running in Multan).
• Biometric Transfer Feasibility: Under current Punjab Excise rules, biometric verification of the registered seller is mandatory. Never execute a purchase on an open transfer letter.

2. Paint Thickness & Structural Pillar Integrity

Superficial cosmetic polishing often masks major collision damage:

• Factory Paint Thickness: Factory OEM paint measures between 80 and 130 microns.
• Filler & Repaint Detection: Any reading over 250 microns indicates putty/body filler, signaling prior impact damage.
• A, B, and C Pillars: Inspect the spot welds inside the door frames. Irregular welds or missing factory seam sealer indicate rolled-over or t-boned body shells.

├── Engine Compression & Oil Blow-by
├── Computerized OBD-II DTC Error Codes
└── Transmission Fluid Condition & Shift Smoothness

3. Computerized OBD-II Diagnostics

Modern vehicles store historical error codes in their Engine Control Module (ECM):

• Verify that the Check Engine light illuminates when the ignition is switched on and extinguishes within 3 seconds of engine start. If it never illuminates, the bulb may have been disconnected to hide catalytic converter or sensor failures.
• Run a live diagnostic scan to detect hidden misfire cycles, transmission slip ratios, and ABS module faults.
