Brisbane knows flooding, and every event leaves behind vehicles their owners are unsure what to do with. Flood-affected cars are among the hardest to value accurately, because the damage is almost never limited to what you can see.
Why water damage is different
Collision damage is localised. A car hit in the front may have an entirely intact rear half, and everything behind the impact remains recoverable.
Water does not behave that way. It reaches the wiring looms, the electronic control units, the seat frames, the carpet underlay, the door cards, the airbag modules and the differential and gearbox oil. Damage is distributed rather than concentrated, which cuts parts recovery substantially.
That is the core reason a flood-damaged vehicle is generally worth less than a collision-damaged vehicle that looks far worse.
How high the water reached
This is the single biggest factor, and it is worth being precise about.
Below the floor pan. Often the least serious. The driveline may be unaffected, and much of the vehicle remains recoverable.
Above the floor, below the seat base. Carpet, underlay and some wiring affected. Interior components compromised. Mechanical parts frequently still recoverable.
Above the seat base or dashboard. Serious. Electronics, airbag modules, instrument cluster and the majority of the loom are affected. Parts value drops sharply.
Fully submerged. Value sits largely in metal weight and a small number of components.
If you know roughly where the waterline sat, say so when asking for a quote. It changes the figure more than almost anything else.
Fresh water versus salt water
Salt water is markedly more destructive. Corrosion continues after the vehicle dries, and it works through electrical connections and body cavities long after the event. A vehicle affected by tidal or storm-surge water is generally worth less than one affected by river or rainwater at the same depth.
What still holds value
Even a heavily affected vehicle retains recoverable value:
- Body panels, which are unaffected by water sitting inside the cabin
- Wheels and tyres
- Glass
- The catalytic converter, which is unaffected by immersion
- Metal weight, which does not change
Insurance write-offs
If the insurer has settled and declared the vehicle a write-off, the classification matters. A statutory write-off cannot return to the road, and its value is entirely in parts and metal. Where you were offered the option of retaining the wreck for a reduced settlement, knowing the salvage figure lets you compare properly rather than guess.
What not to do
Do not attempt to start it. Water in the cylinders can cause serious internal damage the moment the engine turns over, and it can turn a recoverable engine into scrap.
Do not spend money drying or cleaning it before getting a valuation. It rarely changes the offer enough to justify the cost.
Getting an accurate number
Describe how deep the water reached, whether it was fresh or salt, how long the vehicle sat in it, and whether it has been started since. Those four facts produce a specific quote rather than a cautious one.
Photographs help — the interior, the carpet and the engine bay tell more than the exterior does.
