2006 Saab 9-3 1.9L Diesel · SL56 SUX

The most recent MOT test in November 2021 at 119,287 miles reveals a vehicle with a worsening trend regarding structural corrosion, though it passed the roadworthiness standard on the same day as an initial failure. The tester flagged general underbody corrosion and corroded rear strut mounts, indicating long-term exposure to moisture and potential underseal degradation. Front tyres repeatedly wear to the legal limit and on the edges, suggesting suspension geometry issues or persistent neglect of basic consumables. The brake pipes have been consistently flagged as corroded and covered in grease or other material since at least 2020, pointing to a failure to address a critical hydraulic vulnerability. Maintenance appears reactive rather than preventative, with the owner rectifying immediate failures like the windscreen washer and tyres but leaving structural rust and corroded brake lines unrectified. The recorded mileage of 119,287 miles equates to roughly 5,964 miles per year, which is exceptionally low for a 2006 vehicle. Between the May 2019 test at 99,475 miles and the November 2020 test at 117,085 miles, the car covered 17,610 miles in a single year, a sharp spike compared to the subsequent year where it recorded zero mileage between November 2020 and November 2021. This erratic pattern suggests periods of prolonged standing interspersed with intense use. Long stationary stints often exacerbate the corrosion issues noted on the brake lines and underbody, as moisture sits undisturbed rather than being blown dry by regular driving. A prospective buyer must thoroughly inspect the structural integrity of the underbody and rear subframe, given the repeated tester notes regarding corrosion. The rear strut mounts and corroded brake pipes require close scrutiny; any flaking metal or weeping fluid from the lines indicates an immediate failure risk. Examine the suspension components closely. The 2019 failure highlighted a worn nearside rear anti-roll bar bush and a degraded ball joint dust cover, typical wear items that may have deteriorated further despite the recent low mileage. Check the condition of the exhaust system, as a major leak was flagged in 2019, and verify the front tyres for uneven edge wear, which points to potential tracking issues or worn suspension bushes. The recurring corrosion advisories suggest the previous owner prioritized passing the test over long-term preservation.
