What you are looking at

No photograph available

We do not hold a verified photograph of the Body corrosion yet. We would rather show none than show a picture of a different part.

What goes wrong

As a 20-plus-year-old Japanese import, the Spacio is prone to corrosion on cars that have lived near the coast or on salted or gravel roads. Rust typically starts in the sills, wheel-arch lips, floor pan seams, subframe and suspension mounting points, and can develop from the inside out where mud and moisture collect. Structural rust in these areas can fail a NZ WoF and be expensive to repair properly.

What you would notice

Bubbling paint or flaking on sills and wheel-arch edges
Visible surface or scale rust on the underbody and floor seams
Rust around subframe and suspension mounting points
Damp or musty carpets over rusted floor pan

How to check it

Where to look. Underbody, sills, wheel arches, floor pan and suspension mounting points

Inspect the sills, wheel-arch lips, floor pan, boot floor, subframe and suspension mounting points from underneath for scale rust or holes, and press suspect areas for softness; lift the boot and cabin trim to check for perforation. Coastal-region cars and those on salted roads are at higher risk. Any structural rust is a WoF and repair concern.

Parts involved: Body corrosion.

What it costs to put right

$200 to $3,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the car lived near the coast or been rustproofed?”
“Does it have a current WoF and any rust-related advisories?”
“Can I see the underbody on a hoist?”
