Introduction to Pre-Purchase Inspections
Buying a used car in Auckland or anywhere in New Zealand can be a smart way to save money. However, with recent floods affecting many areas, including Auckland, Hamilton, and Wellington, there’s a heightened risk of unknowingly purchasing a “flood car”—a vehicle damaged by water and silt. A pre-purchase mobile inspection is essential to help buyers identify hidden damage before committing.
We’re Oil Pro, a local Kiwi-owned company based in Auckland, dedicated to helping you make a safe, informed choice. With our engineering expertise and mobile inspection service, we bring the workshop to you, inspecting every vehicle thoroughly.
This guide covers what to expect from a professional pre-purchase inspection, key signs of flood damage, and how to protect yourself when buying a used car in New Zealand.

Why Pre-Purchase Inspections Matter in Auckland and Beyond
New Zealand’s used car market is vibrant, with many buyers seeking reliable vehicles in cities like Auckland, Christchurch, Tauranga, and Napier. However, recent floods have increased the risk of flood-damaged cars circulating in the market.
Flood cars often have hidden issues that can cause expensive repairs or safety risks down the line. A thorough pre-purchase inspection can uncover these problems early, saving you from costly mistakes.
- Flood Damage Risks: Water can damage electrical systems, engines, and interiors.
- Silt and Corrosion: Silt left behind after floods accelerates rust and component failure.
- Resale and Safety: Buying a flood car can affect resale value and compromise safety.
Professional inspections, like those offered by AA Pre Purchase Inspections, include detailed checks to detect these risks before you buy.

What a Pre-Purchase Inspection Includes
A comprehensive pre-purchase inspection typically involves a 100+ point visual and functional check conducted by experienced mechanics. Here’s what it covers:
- Visual Checks: Bodywork, paint inconsistencies, silt or mud deposits, water stains inside the vehicle.
- Mechanical Inspections: Engine condition, transmission, brakes, suspension, exhaust system.
- Electrical Systems: Checking wiring, lights, dashboard electronics, and battery health.
- Undercarriage Examination: Rust, corrosion, and silt deposits indicating flood exposure.
- EV/Hybrid Main Battery Test: For electric or hybrid vehicles, testing battery health and performance.
- Road Test: Evaluating vehicle drivability, unusual noises, and handling.
In New Zealand, organisations like the New Zealand Automobile Association (AA) inspect over 10,000 cars per year, ensuring buyers get detailed reports to make informed decisions.

How to Spot Flood Damage Yourself
While professional inspections are best, you can do some basic checks to spot possible flood damage:
- Check for musty or damp smells inside the car.
- Look for water lines or residue in door jambs, glovebox, and trunk.
- Inspect carpets and upholstery for damp patches or discoloration.
- Test all electrical components like windows, locks, and lights.
- Look under the bonnet and undercarriage for silt, mud, or rust.
- Check for mismatched paint or new parts that may cover damage.
If you notice any of these signs, a full pre-purchase inspection is highly recommended to avoid buying a flood-damaged vehicle.
