1991 Mercedes-Benz 190 E 2.0L Petrol · J506 CGK

Corrosion is the dominant theme across the MOT record, with repeated advisories for front and rear brake pipe rust and greasing, plus progressive front‑body integral structure corrosion noted from 2019 onward; a 2021 failure added excessive wear on both front anti‑roll‑bar linkage bushes, while a 2020 failure highlighted a holed rear‑exhaust pipe and a non‑functional front position lamp. The most recent test in December 2022 passed, yet the same front‑body corrosion advisories re‑appeared, indicating that the underlying rust has not been remedied and remains a persistent risk to structural integrity and brake system reliability. At 120,588 mi for a 1991 model the average annual mileage works out to roughly 3,400 mi, well below typical usage for a car of this age. The low accumulation suggests periods of limited running or extended storage, which can exacerbate rust formation on exposed chassis and brake pipe sections, especially where moisture can settle. The MOT history shows no large gaps in testing, with annual examinations since 2017, but the mileage increments between tests are modest, reinforcing the inference of light duty rather than high‑stress operation. Prospective buyers should give the brake system a thorough inspection. Inspect all front and rear brake pipes for visible rust, pitting, or signs of leakage at the joints and flexi‑hose connections; any dampness or corrosion‑related cracking could compromise hydraulic pressure and lead to spongy pedal feel or reduced braking efficiency. During a road test, feel for a soft or sinking brake pedal, uneven braking force between wheels, and listen for any hissing or fluid movement that could indicate a pipe breach. Given the historic “slightly deteriorated” hose advisories, replace any hoses that show surface rust or loss of flexibility, and consider a full flush of the brake fluid to remove any contaminant that may have entered through the corroded pipes. The front‑body integral structure corrosion adjacent to the jacking points, recorded on both nearside and offside in 2019, 2020 and 2022, warrants a detailed visual and tactile survey of the subframe and floor panels. Look for flaking paint, rust holes, or softened metal around the jacking points and the lower front sills; any structural weakening could manifest as a flexing sensation when applying the brakes or steering over bumps. Additionally, verify that the front position lamp now operates correctly and that the rear‑exhaust pipe is intact, as the 2020 failure indicated a major leak that could affect emissions compliance and produce a noticeable exhaust rattle. A test drive should include a steady‑speed run to listen for exhaust leaks and a check for any steering pull or vibration that might be linked to the previously worn anti‑roll‑bar bushes, which may now be approaching the end of their service life.
