2005 Mazda 3 2.0L Petrol · DY55 AJX

The Mazda 3 passed its most recent MOT on 15 February 2023 at 62,879 miles, but the surrounding record shows a worsening structural trend. Three weeks earlier, on 30 January 2023 at 62,757 miles, the tester failed the car on six separate excessive corrosion points across both front and rear sills and wheel arches, each seriously affecting structural strength within 30cm of body mountings. The owner corrected these for the pass, yet the recurrence of pitting on the front brake discs in both tests confirms an unresolved wear pattern. This is not a stable history; the chassis required major intervention before the last certificate could be issued. At roughly 21 years old the car shows 62,879 miles, an average of under 3,000 miles per year. The odometer moved only 1,033 miles between the February 2020 test at 47,023 miles and February 2022 at 56,056 miles, then just 6,823 miles to the 2023 tests. Such low annual use over two decades often means long stationary periods, which accelerates sill and arch corrosion as seen in the 2023 failure. The 2022 entry already noted plastic covers hiding the outer sills, so the rot was obscured until the 2023 strip-down. A buyer must inspect the near and offside front and rear sills and wheel arches in person for weld repairs or filler from the January 2023 corrosion failure. The DVSA record proves the metal was compromised at body mountings; verify the fix holds and has not spread behind seams. The front brake discs scored and pitted at both 2022 and 2023 tests despite the pass, so measure disc runout and thickness and check for binding calipers. The 2022 pass flagged rear pads low, offside rear anti-roll bar link play, and a deteriorating plate; treat the suspension bushes and rear brake balance as due for renewal. Previous keepers skipped visible upkeep on consumables and let structure rot to a serious level before acting. Given the age and corrosion history, a professional underside inspection on a ramp is essential before purchase.
