2007 Chrysler 300 C 3.0L Diesel · X77 NGH

A pattern of late-life corrosion and recurring tyre issues defines the roadworthiness profile of this 2007 Chrysler 300 C. Across eight recorded MOT tests, the vehicle has passed six times and failed twice, with both failures occurring at relatively recent inspections. The most recent test on 23 May 2026 resulted in a pass, but it was accompanied by an advisory noting corrosion on the front suspension components on both sides, flagged under section 5.3.3 (b) (i) as not yet seriously weakened. The 2024 failure was particularly concerning, recording a dangerous defect for nearside rear tyre tread depth below the 1.6mm legal minimum and a major defect for fitting tyres of different structures across the same rear axle. Just over a year earlier in April 2023, both rear tyres were already under advisory for being worn close to the legal limit and worn on their edges, indicating that rear tyre wear had been developing for some time before culminating in the dangerous failure. The earliest recorded failure, in March 2019, related to an ineffective windscreen wiper accompanied by a lower suspension arm bush advisory, suggesting that suspension component wear has been an intermittent theme over the vehicle's testing life. With a recorded mileage of 93,944 against an age of roughly 19 years, this Chrysler has accumulated at approximately 4,944 miles annually, which is notably low for a vehicle of its vintage. There are no extended gaps in the MOT testing record that would suggest long periods off the road, and the mileage progression between tests is broadly consistent with occasional or low-intensity use. Mechanically, lower annual mileage can reduce wear on high-mileage consumables such as the clutch, drivetrain and engine internals, but it can also accelerate certain age-related deterioration. Standing periods encourage corrosion in brake calipers, surface rust on discs, stiffening of suspension bushes, and seal drying in hydraulic components. Combined with the recorded front suspension corrosion advisory, the usage pattern is consistent with a vehicle that has aged through standing time as much as through driven wear. For a prospective buyer, the most pressing areas to inspect are the front suspension and the rear tyres. The advisory on both front suspension components showing corrosion on 23 May 2026 warrants a close physical examination for any flaking, deep pitting or section loss around control arms, anti-roll bar drop links and mounting brackets, particularly where metal wraps around bushes. On a test drive, listen for clonks or knocking noises over uneven surfaces, pay attention to any vagueness or looseness in the steering on turn-in, and feel for wandering at speed which could indicate worn ball joints or compliant bushes. The rear axle tyre history also demands attention: with advisories in 2023 for edge wear on both rear tyres and a 2024 dangerous failure involving both tread depth and mismatched tyre structures, alignment geometry and any pre-existing kerb damage to the rear wheels should be checked. Uneven shoulder wear on the current rear tyres, or any feathering pattern, could point to a camber or toe issue on the rear suspension that may itself be linked to the same corrosion concerns flagged at the front. A thorough physical inspection should also cover the components that have already produced advisories or failures historically, even where no current defect is recorded. The 2019 lower suspension arm bush advisory at the nearside front means the rubber may have hardened, cracked or perished over the intervening years, and any movement when the wheel is levered by hand would confirm a need for replacement. Brake components deserve close scrutiny given the low-mileage profile, as seized calipers and corroded brake pipes are common on vehicles that see limited use, and a firm pedal with uneven pulling under braking would indicate binding or hydraulic issues. The wiper linkage failure from 2019 is unlikely to recur, but checking that the wipers park correctly and clear the screen across the full sweep is worthwhile. Given the 2024 dangerous tyre failure, the spare wheel condition, age and tread depth of all four fitted tyres, and the presence of a working tyre pressure monitoring system should be verified before purchase, as the previous record demonstrates that rear tyre condition on this vehicle can deteriorate rapidly between tests.
