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

The Life is a JDM kei car built for a domestic market with modest underbody rust protection, and cars that spent years in northern Japan can arrive already salted, while examples living near the NZ coast then face persistent salt air. On a light monocoque like this, corrosion tends to start on the underbody rails, suspension mounts and subframe, the rear wheel arches and sill seams, and around the tailgate and window rubbers, and in bad cases it becomes a WOF failure on structural rust. Because these cars are old, cheap and often not garaged, rust is frequently the deciding factor between a tidy example and a scrapper regardless of how well the engine runs. This entry reflects the general Japanese-import corrosion pattern rather than a Life-specific defect study, so it is seeded for buyer awareness rather than verified; a thorough underbody and arch inspection is the safeguard.

What you would notice

Surface or bubbling rust on rear wheel arches, sills and door bottoms
Flaky corrosion on underbody rails, subframe and suspension mounts
Rust staining around the tailgate, window rubbers and seams
Fresh underseal or overspray hiding corrosion underneath

How to check it

Where to look. Underbody rails, subframe and suspension mounts, rear wheel arches, sills and tailgate/window seams

Put the car on a hoist or look underneath for scaling or holed metal on the floor rails, subframe and suspension mounting points, and probe the rear arches, sills and door bottoms for bubbling or soft spots. Be wary of fresh underseal that could be hiding rot, check for a recent WOF and any rust-related advisories, and treat any structural corrosion as a walk-away or heavy negotiating point given the car's low value.

Parts involved: Body corrosion.

What it costs to put right

$200 to $2,500 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

“When was the last WOF and were any rust items noted?”
“Has the underbody or arches ever been repaired, welded or re-undersealed?”
“Is the car garaged, and has it lived near the coast?”
“Can I put it on a hoist to inspect the underbody before buying?”

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

Honda Life buyer questions

Is underbody and arch corrosion on japanese kei imports in nz coastal use - seeded serious on a Honda Life?

How much does it cost to fix on a Honda Life?

$200 to $2,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Honda Life years are affected?

Our research records this fault on the 1998–2014 Honda Life. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
