2019 Mercedes-Benz C 1.5L Petrol · LL19 OTW

A pattern of progressive tyre wear dominates the roadworthiness history of this 2019 Mercedes-Benz C-Class and is the most consistent mechanical theme across the recorded tests. The earliest inspections in 2022 and 2023 returned clean passes with no advisories, but by the 2024 test the nearside front and both rear tyres were flagged for slight cracking and perishing, and in 2025 the nearside and offside rear inner edges were noted as being worn close to the legal limit. The situation escalated at the April 2026 attempt when an offside front tyre with exposed ply or cords on the inner edge resulted in a dangerous failure, alongside advisories on both front tyres and both rear tyres for inner-edge wear approaching cord visibility. A retest six days later on 8 April 2026 recorded a pass, but the advisories for the nearside front and both rear tyres remained, with the rear pair additionally flagged for heavy cracking in the tread. The trend is clearly worsening rather than stable, with edge wear concentrated on the inner shoulders rather than uniform tread reduction. Against a seven-year vehicle age, 41,358 recorded miles equates to an average of roughly 5,900 miles per year, which is low and consistent with a vehicle that has seen limited daily use or has experienced periods of inactivity. Such low annual accumulation reduces wear on major drivetrain and braking components but can simultaneously accelerate certain age-related deterioration, particularly in rubber compounds, flexible boots, and brake hydraulic seals that suffer from underuse. The testing record covers consecutive annual entries from 2022 through 2026 with no gaps, suggesting the car has remained in regular use or at least has been presented for inspection each year, and there is no evidence of a long lay-up that would introduce separate concerns around brake seizure or fuel system degradation. For a prospective buyer, the immediate priority is a thorough tyre inspection rather than any assumption that the advisory items are minor. The repeated inner-edge wear pattern on both front and rear axles is characteristic of either incorrect wheel alignment, particularly excess negative camber, or worn suspension components allowing the wheel geometry to drift out of specification. On a test drive, pay close attention to steering pull to either side under braking, any tramline tracking following road surface undulations, uneven steering wheel self-centring, or clonking or knocking from the front suspension over speed bumps, as these symptoms often accompany the kind of geometry drift flagged here. Inspect the rear suspension bushes and trailing arms for cracking or deformation, as perished rear bushings on the C-Class can also contribute to inner-edge tyre wear. The cracking and perishing noted across multiple tyres in successive years warrants careful examination of the sidewalls and tread ribs for visible ozone cracking, bulging, or exposed cord, particularly on any tyres that have remained fitted for several years regardless of mileage. Given that the cords were exposed on the offside front at the April 2026 test, a complete four-tyre replacement with alignment verification should be budgeted for, alongside a four-wheel laser alignment check to confirm whether the underlying cause of the inner-edge wear has been addressed. Beyond the tyres, listen for any brake judder or vibration through the pedal on initial application, as low mileage combined with sporadic use can lead to disc corrosion and pad glazing even without recorded advisories on those components. A physical inspection of the underside for any oil residue around the engine and gearbox sump, and a check for dampness around the power steering rack, would round out a sensible pre-purchase evaluation given the vehicle's age.
